#### Abstract

The modern level of knowledge development in the field of fundamental sciences makes it possible to reliably investigate the processes of evolution. The purpose of our research was to determine the need to establish the existing evolutionary transformations in resistance to abiotic and biotic stress factors of the biosphere in a grape plant, which may be natural for all horticulture crops, and on the other hand, based on the postulate of natural and experimental evolution, to prove the processes of natural evolution as a result of experimental breeding. The results obtained in the study of particular issues of genetics of grapes, based on the existence of general biological regularities, can be prolonged for interpretation, with reference to other horticulture crops. We studied the genetics of grapes, in particular crossability, the inheritance of signs and characteristics, the establishment of regularities in the display of selection value, and heterosis, allowing us to formulate the principles of modeling a new variety. Investigating the process of creating grape varieties that are resistant to biotic factor, it was suggested to consider it from the point of view of the coevolution of the plant and pathogen.

#### 1. Introduction

Genetic resources of Vitaceae grape family from the various centers of origin and vine-growing regions in the world were taken from one of the oldest Eurasian collections of grapes at the All-Russian National Research Institute of Viticulture and Winemaking (ARNRIVW) "Magarach." They have been studied on display of genetically determined sign of frost and mildew resistance. It is established that the grape frost and mildew resistance sign in genome was formed and fixed by evolution at separate forms in the various centers of origin. Suggested sources of high frost and mildew resistance of various botanical taxa from the various centers of origin for selection of frost- and mildew-resistant grape varieties are selected also.

Regularities governing the expression of resistance to Plasmopara viticola (Berk. and M.A. Curtis) Berl. and De Toni, Uncinula necator (Schwein) Burrill, and Botrytis cinerea Pers., the causing agents of mildew, oidium, and gray rot, respectively, and the inheritance of this characteristic in the F1 progeny were established in grapevine.

The nature of the inheritance of resistance to these pathogens in grapevine seems to be identical despite the fact that they differ in the ecogeographical origin, biological characteristics, and the form of host-pathogen relations (obligate/facultative, pathogenic/saprophyte types). The inheritance of resistance obeys the principle of hypothetic heterosis, which means that the progeny does not contain forms with resistance superior to that of the more resistant parent but does contain forms with resistance surpassing the average level of resistance of the two initial forms. Evidence was also gained in support of the theory suggesting that forms of grapevine with resistance to pathogens emerge only in the course of long-term coevolution of the biological objects. Basic principles of grape breeding were established and confirmed by the findings arising from the search of initial forms of grapevine and by the highlighted regularities governing the inheritance of resistance to pathogens in the crop. Breeding for resistance to pathogens was viewed as a specific target without respect to other desired characteristics since this issue was tackled with an aim to determine breeding and genetic regularities of the process and, for the first time, in terms of the interaction of two biological objects, the host plant and the pathogen, each with its own variation and evolutionary patterns.

V. labrusca L., and 64 samples of the cultivated vine V. vinifera sativa D.C., including varieties V. vinifera occidentalis Negr., V. vinifera pontica Negr., and V. vinifera orientalis Negr. and 30 hybrids of V. vinifera L. were studied. The study of resistance to frost and agrobiology study of samples were carried out by the method of ampelographic description and agrobiology evaluation of grapes [1]. The degree of damage to annual shoots was assessed on a scale from 0 to 5 on the degree of damage to the phloem, and the analysis of the restoration capacity of the bush on the fruit links and perennial wood was carried out according to the percentage of blossoming shoots on a scale from 0 to 9 points. Estimation of resistance to mildew from 1 to 9 points was carried out according, as well as to frost, to OIV descriptor [2] on the basis of long-term observations (2000–2017) in the years of mildew epiphytotic. A higher score characterized less damage or better restoration ability of the plant, which reflects its higher resistance to stress factors or abiotic (frost) or

The research was done using a total of 28 hybrid populations of grapevine obtained via hybridization of 31 initial forms, of which 23 and 14 forms entered as the female and the male parents, respectively, and 6 forms were used in both qualities. The genetic resources employed consisted of 1378 hybrid forms belonging to hybrid populations, each containing at least 25 forms [4]. This enabled good reliability of results indicating the inheritance of the characteristic in the progeny [5]. The reliability of the results was confirmed statistically [6]. Initial forms differing in resistance to the causing agents of mildew, oidium, and gray rot (Plasmopara viticola Berl. et de Toni, Uncinula necator Burr., Botrytis cinerea Pers.) were chosen with a view to establish regularities governing the expression of the characteristic in the F1 progeny.

The existence of different centers of origin of cultivated plants and grapevine in particular suggests formation of specific biological features in the autochthonous varieties in those centers in the process of evolution. The biological specificity of the autochthonous grapevine varieties was to gain a foothold at the genetic level. At the same time, expression of these traits in the progeny should also be specific. The conducted research has shown that crossing capacity of the Crimean autochthonous grapevine varieties with the varieties and forms of different species and ecogeographical origin has a specific characteristic and proves that crossing capacity can be perceived as an independent genetically determined biological feature.

Global and local climate changes demanded creation of new cultivars, in particular in viticulture. Thus, the problem of breeding new grapevine cultivars that would correspond to the present-day biosphere conditions emerged. As an answer to this, an immunobreeding program "Analogue" was developed at the "Magarach" Institute. The program aims at improving the efficiency of grape breeding and achieving cultivars that would comprise resistance to a variety of pests, diseases, and unfavorable environmental factors and would, at the same time, produce fruit of the quality that would be comparable to the best samples of their international analogues.

The suggested concept of the models is based on 16 most desired selection traits that had been chosen from the existing selection pool, identification of the original forms for crossbreeding, and multivariate analysis. To facilitate cooperation with other research centers, the information obtained was encoded according to the International Organisation of Vine and Wine (OIV)-Bioversity International descriptor.

Using the developed models for the creation of new cultivars will, on the one hand, help solve ecological problems in the vineyards and, on the other, ensure high economic effectiveness of viticulture and winemaking and, at the same time, obtain grape cultivars for different purposes.

The research was conducted by the Department of Breeding, Genetics and Ampelography of the All-Russian National Research Institute of Viticulture and Winemaking "Magarach" on the field of plant breeding plots located on the southern coast of the Crimea and on the hydroponic culture of the vegetation plot in the period of 2008–2015. The seedlings were grown on gravel in hydroponic channels. For the cultivation of grape seedlings, we used chemically inert fraction of diorite aggregate sized 3–5 mm, which is a good conductor of the nutrient solution to the plant roots that keeps water on its surface well, serves as a support for the roots, and provides good aeration of the root system. For the growth of grape seedlings, we used hydroponic solution of variable composition [9, 10].

Mobilization of genetic resources of grapes in ampelographic collections, as shown by scientists of many countries [15–17], plays an important role in the conservation and use of the gene pool of grapes. One of the important tasks of collecting and preserving the gene pool of the genus Vitis in many countries of the world is the preservation of local varieties of grapes that are exclusively part of the natural heritage and do not grow in other vine-growing regions [18, 19]. Most of the local and uncommon varieties of grapes are now preserved only through collections [20]. It is known that the local assortment of grapes has been formed for a long time under certain conditions of a specific region and has a number of valuable features [21]. The study of the genetic resources of grapes collected on ampelographic collections from different centers of origin of grapes will allow us to identify new sources for breeding, to form an idea of the evolution of the grape culture.

Genetic resources of the grape of the "Magarach" Institute are collected in an ampelographic collection, one of the largest and oldest collections of grapes in the world, which was noted at international scientific forums and Internet sites [22]. The beginning of the formation of the collection dates back to 1814 and the existence of the "Magarach" Institute (1928) and coincides with the period of the beginning of collecting varieties of vine in Europe. The uniqueness of the collection of the Magarach Institute is that over two centuries it was replenished with samples from various vine-growing regions of the world, Europe, Asia, Africa, and North

As male initial forms, we used 3 Crimean autochthonous grape varieties ('Shabash', 'Kokur Belyi', 'Gevat Kara'); 3 autochthonous varieties from other centers of origin of grapes ('Rkatsiteli', 'Chardonnay', 'Sauvignon vert'); 2 varieties of the Institute of "Magarach" selection ('Bastardo Magaraci' and 'Rubinovyi Magaracha'), derived by crossing within the species of Vitis vinifera; and 11 interspecific varieties ('Podarok Magaracha', 'Citronnyi Magaracha', 'Aurora Magaracha', 'Pervenets Magaracha', 'Riesling Magaracha', 'Spartanets Magaracha', 'Krasen', 'Antey Magarachsky', 'Alminskyi', 'Granatovyi Magaracha', and 'Pamyati Golodrigi').

We studied hybrid seed formation, fully formed seed (seeds with a viable germ and well-developed endosperm) formation, seed germination, and development of seedlings, including vigorous ones as they are most viable and potentially more productive.

The study and selection of seedlings were conducted based on the methodology developed by the Department of Breeding, Genetics and Ampelography of the "Magarach" Institute [11]. The degree of the manifestation of traits was coded [12].

Increased frost resistance is also possessed by some cultural representatives of the species Vitis vinifera L. due to the high ecological plasticity of the species. Under the influence of natural and artificial selection in various regions of formation, some varieties of cultured grapes have acquired adaptive properties with respect to low negative winter temperatures. Such varieties are of particular value for breeding, because unlike wild representatives of the genus Vitis, they do not carry the heredity of wild genotype, which reduces the quality of grapes and wine in hybrid forms in the heredity. In general, analyzing the safety indices of the main and replacement buds, the degree of frost damage of the annual vine, as well as the restoration ability of Vitis vinifera L. varieties, according to the degree of frost resistance, they can be divided into three groups:

('Aligoté', 'Cabernet-Sauvignon', 'Merlot', 'Riesling', 'Italia', 'Riesling Rhine', 'Sauvignon Green'), cultivars Vitis vinifera pontica Negr. ('Rkatsiteli', 'Saperavi'), and cultivars-hybrids Vitis vinifera L., parental forms of which have increased resistance to frost: 'Odesskii chernyi' ('Alicante Bouschet' 'Cabernet-Sauvignon') and 'Sukholimanskii belyi' ('Chardonnay' 'Plavay').

A comparative analysis of the regenerative capacity of bushes after the defeat of extreme winter frosts by groups of different origin showed (Figure 1) that the wildest species of the Vitaceae L. family are the highest adaptive capacity, the less the hybrids Vitis vinifera L. Vitis amurensis Rupr. 53.8% of bloomed shoots on fruit segments and 68.8% of blossom shoots on perennial wood. Below these, the Vitis labrusca L hybrids: 35.0 and 66.2%, respectively. Varieties of complex interspecific origin have an average of 12.5 and 16.0% of blossoming shoots on fruit segments, but in terms of the number of restored shoots, they exceed the local varieties Vitis vinifera occidentalis Negr. and Vitis vinifera pontica Negr.

Mildew resistance studies have shown that 27 species of the Vitaceae Lindley grape family possess the highest possible. The assessment of the degree of resistance was 9 points (Figure 2). Also the hybrids of Vitis riparia Michx. possess the maximum resistance to mildew among which are 'North White', 'Taiga Emerald', and others with an average resistance score of 9.

In cultivars-hybrids Vitis vinifera L. Vitis amurensis Rupr., average resistance is 8.6 points. The degree of resistance is 9 points for 'Aksay', 'Golubok', 'Far Eastern Tikhonov', 'Dyushes', and 'Zarya Severa'; the degree of resistance is 7 points for cv. 'Anushayut', 'Bruskam', 'Karin', 'Kunlean', and 'Russian early'; and the degree of resistance is 5 points for cv. 'Cherry Early', 'Dniester Pink', and 'Negru de Yaloven'. In the cultivars-hybrids of Vitis labrusca L., the average score of resistance is 8.6, among them are resistant cultivars (9 points): 'Alpha', 'Lyathes', 'Romulus', 'Lusay'l', and 'Isabella'. The cultivars 'Madella', 'Menu', and 'Lydia' had 7 points.

Less resistant varieties of complex interspecific origin have an average resistance score of 8.06. Varieties with maximum resistance of 9 points include 'Antey Magarachsky', 'Bianka', 'Aurora', 'Golubok', 'Golden Muscat', 'Podarok Magaracha', and 'Tair'. Relatively resistant varieties with a degree of resistance of 7

Increased frost resistance is also possessed by some cultural representatives of the species Vitis vinifera L. due to the high ecological plasticity of the species. Under the influence of natural and artificial selection in various regions of formation, some varieties of cultured grapes have acquired adaptive properties with respect to low negative winter temperatures. Such varieties are of particular value for breeding, because unlike wild representatives of the genus Vitis, they do not carry the heredity of wild genotype, which reduces the quality of grapes and wine in hybrid forms in the heredity. In general, analyzing the safety indices of the main and replacement buds, the degree of frost damage of the annual vine, as well as the restoration ability of Vitis vinifera L. varieties, according to the degree of frost resistance, they can be

A considerable amount of research into the capacity of hybridization in grapevine and the inheritance of characteristics, including resistance to mildew, oidium, and gray rot in the F1 progeny, has been done in the "Magarach" Institute. Regularities governing the expression of the biological specificity of the capacity of hybridization or the inheritance may be either general or particular; one can speak about either general biological regularity, the nature of the combining ability of two definite forms of grapevine, or the possibility to observe a certain degree of the

Ecogeographical foci of origin of initial forms, the interrelationships of these foci with the origin of individual groups of forms which may be grouped into botanical taxa, the degree of genetic relatedness of forms obtained via inbred and distant hybridization, the resistance of initial forms to a given pathogen, the presence of forms with different levels of resistance (assessed by use of a numerical scale) in the progeny, and the average resistance scores across the population may serve as the key elements in considering different approaches in attempting to examine the outcome of breeding varieties and forms of any crop, including grapevine, for resistance to pathogens. All this helps investigate the genetics of the inheritance of resistance. The results obtained may be interpreted from a standpoint of the abovementioned approaches, e.g., a genetic formula of initial forms may be described, these initial forms may be assessed as sources and/or donors of the characteristic in question, and the effectiveness of the transmission of the characteristic during hybridization with definite individual forms may be determined. The influence of abiotic factors on the effectiveness of the capacity of hybridization in grapevine and the effectiveness of the transmission of characteristics to the progeny

In order to develop breeding programs, including those aimed to achieve grape varieties resistant to pathogens, we need to know the biological peculiarities of the plant and the specificity of desired characteristics. Breeding grape varieties for resistance to biotic factors may require consideration of the biology and

Though the causing agents of mildew, oidium, and gray rot are all fungi, they do differ biologically. Plasmopara viticola and Uncinula necator, the causing agents of mildew and oidium, respectively, are capable to grow only on grapevine as the obligate pathogens, while Botrytis cinerea, the causing agent of gray rot, is a cosmopolite, polyphage, and saprophyte.

The average resistance score for cultivars of V. vinifera sativa D.C. is 1.2. Most cultivars of V. vinifera sativa D.C. are not resistant to mildew as the evolutionary pathogen and variety samples of this species were developed in different centers of origin of the grapes and were geographically isolated. These are such varieties as 'Cardinal', 'Kishmish black', 'Goruli mtsvane', 'Kok habah', 'Murza raisin', and 'Artin zerva'.

Relative resistance to the pathogen is noted in some local varieties like 'Chausch black', 'Chilar', 'Chinuri', 'Chol Ber', 'Shaani white', 'Shaani black', 'Aygesard', 'Bayan shirei', 'Varyushkin', 'Tresso black', 'Vereya', 'Chersonesus', 'Hindogny', and 'Tsolikouri', whose resistance levels were 7 points, and varieties 'Chausch white', 'Albilo Crimean', 'Mattrassa', 'Misket Cherven', 'Sabash', whose resistance level to mildew was 5 points.

Botanical diversity of grapes culture, reflected in the classification and taxonomy of varieties and forms of the grape Vitaceae family, reflects the process of natural evolution and natural and artificial selection. Scientists in various countries in the eighteenth to twentieth centuries carried out a grandiose work that made it possible to differentiate representatives of the Vitaceae family in botanical taxons. The conducted researches established that all this botanical variety of the Vitaceae family was formed in different centers of origin of the grape culture on the planet. Depending on the abiotic conditions in the centers of origin of culture, a genome was formed in the form of individual botanical taxa in particular within genera and species differentiated in resistance to abiotic stress factors. Biotic conditions in these same centers of origin formed the genome in the form of the same individual botanical taxa, within the genera and types of grapes as a host plant, differentiated by resistance to biotic stress factors and the pathogen gene in the process of conjugate evolution. In the end result, samples of grapes were formed in each separate center of origin of the culture, differentiated not only according to botanical characteristics but also on a set of biological characteristics, in particular, resistance to biotic and abiotic stress factors of the biosphere, as frost and mildew resistance.

Speciation, specifically the formation of the species Vitis vinifera L., is directly related to the existence of wild forest grapes, belonging to the relics of Eurasia. The studies established a significant difference, including morphological and morphometric features and molecular genetic markers, between forms of wild forest grapes from various regions of Eurasia. Consequently, it may be considered necessary to continue these studies in order to isolate in the centers of origin of the culture of the grapes individual foci or subcenters of origin.

#### 4. Plants as host and pathogen coevolution

Grapevine, like any plant species defined botanically as an independent hierarchical unit, has its own habitat [23], which, in turn, embraces individual foci of origin [24].

For each agricultural crop, including grapevine, both habitats of varieties in commercial cultivation and foci of origin of different botanical forms are determined [3]. Such varieties make up the commercial assortment of a crop, and botanical forms constitute the family of Vitaceae [25, 26]. The objective of this research was to establish genetically determined regularities governing resistance to pathogens in grapevine based on accessions from different foci of origin and newly bred forms obtained via sexual hybridization [27].

A considerable amount of research into the capacity of hybridization in grapevine and the inheritance of characteristics, including resistance to mildew, oidium, and gray rot in the F1 progeny, has been done in the "Magarach" Institute. Regularities governing the expression of the biological specificity of the capacity of hybridization or the inheritance may be either general or particular; one can speak about either general biological regularity, the nature of the combining ability of two definite forms of grapevine, or the possibility to observe a certain degree of the expression of the characteristic in the F1 progeny.

Ecogeographical foci of origin of initial forms, the interrelationships of these foci with the origin of individual groups of forms which may be grouped into botanical taxa, the degree of genetic relatedness of forms obtained via inbred and distant hybridization, the resistance of initial forms to a given pathogen, the presence of forms with different levels of resistance (assessed by use of a numerical scale) in the progeny, and the average resistance scores across the population may serve as the key elements in considering different approaches in attempting to examine the outcome of breeding varieties and forms of any crop, including grapevine, for resistance to pathogens.

Biological differences of the pathogens suggest that the inheritance of resistance to them as a genetically determined characteristic is governed in grapevine by specific regularities.

The advent of complex infection backgrounds has enabled the breeder to assess the newly bred genetic resources for resistance to a set of pathogens and to confirm that hybrids with resistance to the set of the pathogens in question have been achieved provided the appropriate choice of initial forms.

In this stage of scientific knowledge and expertise, the concept of evolutionary development of the flora on Earth is based on the existence of certain centers of origin of cultivated plant species, including grapes [24]. A fundamental contribution to the development of the theory of centers of origin was made by Vavilov [31]. Negrul has further developed this theory [32], highlighting the ecological and geographical areas forming the autochthonous grape varieties. These varieties form separate ecogeographical groups of autochthonous grape varieties. The "Black Sea" area is one of such ecogeographical zones, where autochthonous grape varieties are formed [33]. Within the bounds of this zone, modern scientists have identified specific subcenters of origin of the grapes, one of them being Crimea [21, 34], where relict endemic wild forest vines exist to date. This resulted in the formation of a specific set of autochthonous grape varieties with characteristic biological features in the Crimea, due to which they are used in the breeding programs

It should be noted that the process of breeding new varieties, as a rule, involves analysis of the combining ability of the initial forms with regard to the inheritance of the degree of trait expression in the progeny. At the same time, it has to be kept in mind that in the course of generative hybridization, the formation of a germ and seeds, along with hybridization efficiency, differs between various initial forms, and we can assume that this is a genetically predetermined feature. Therefore, the autochthonous grape varieties of the Crimea are characterized by specific crossability that has become part of their DNA in the process of natural evolution. The

It is known that the majority of the Crimean local grape varieties has a functionally female flower type and is, therefore, not resistant to the biotic and abiotic environmental factors. This affects the stability of fertilization and vine yielding capacity. It is possible to increase the adaptive capacity of the Crimean local grape varieties not only by the selection method but by the hybridization method as well. It is worthwhile to evaluate the hybridization efficiency of the Crimean autochthonous grape varieties, which, first and foremost, require determining the parameters, based on which such studies may be performed. The formation of a new genotype of a plant consists of two principal stages: (1) hybridization, to include formation of berries and seeds, and (2) the development of seedlings and of their

According to the earlier data, the berry formation in different breeding combinations is characterized by biological traits of the initial female plant, while it is not dependent on the male form, which has been supported by the number of berries per bunch of a cross-combination. Therefore, there is no need to consider the number of bunches and berries per bunch in the further study of grape crossing capacity. When assessing crossing capacity, it is more important to pay attention to the number of the formed seeds, including the fully formed ones, as compared to the number of berries with formed seeds, and to the number of seedlings obtained

patterns.

The grape plant, as a biological object, exists and develops in the biosphere, being in permanent contact with and affected by biotic and abiotic factors. Careful consideration is given to the effects of biotic factors on development of a plant organism, including grapevine, due to the specific nature of the phenomenon, the essence of which lies in the fact that two biological objects, the host plant and the pathogen, change as affected by each other and abiotic factors.

The fact that variation of biological objects is governed by the abovementioned regularities enables evolutionary models to be built. Besides, and this is of no less importance, this knowledge can be applied in purposeful creation of forms of a crop which possess a desired set of useful characteristics, including resistance to pathogens. The expression of such characteristics must be high enough to allow cultivation of these forms in the field without appropriate protection measures.

Grapevine may be attacked by pests and diseases whose causing agents are of different natures: viruses, bacteria, and fungi. The biology and the life cycle of the fungi Plasmopara viticola, Uncinula necator, and Botrytis cinerea, the causing agents of mildew, oidium, and gray rot, respectively, have most exhaustively been studied. The development of grapevine as affected by the former, the reaction of the grape plant to damage, and the degrees of resistance of forms, varieties, and different species of the crop to these pathogens have also been studied in detail.

Different degrees of resistance to the causing agents of the abovementioned diseases in individual grape varieties suggest that purposeful breeding of varieties is possible which combines resistance to the set of the pathogens in question and other desired economical characteristics in their genotypes. To this end, we need to know regularities governing the capacity for hybridization of various initial forms and the inheritance of characteristics, including resistance to pathogens, in the F1 progeny. Since grapevine is a vegetative propagated crop, we may limit our studies of the inheritance of characteristics to the F1 progeny, and the transmission of characteristics to the progeny is governed both by the capacity for hybridization of initial forms and their combining ability, which determine the transmission of a characteristic to the progeny and the degree of its expression in the F1 hybrids.

A number of regularities governing the expression of resistance to Plasmopara viticola, Uncinula necator, and Botrytis cinerea, the causing agents of mildew, oidium, and gray rot, respectively, and the inheritance of this characteristic in the F1 progeny were established in grapevine as a result of our long-term research aimed to breed for resistance of the crop to these fungal pathogens. The nature of the inheritance of resistance to these pathogens in grapevine seems to be identical despite the fact that they differ in biological characteristics and the form of hostpathogen relations. The inheritance of resistance obeys the principle of hypothetic heterosis, which means that the progeny does not contain forms with resistance superior to that of the more resistant parent but does contain forms with resistance surpassing the average level of resistance of the two initial forms.

Evidence was also gained in support of the theory suggesting that forms of grapevine with resistance to pathogens emerge only in the course of long-term coevolution of the biological objects. That is why the search for forms of grapevine with resistance to the given pathogens, which remains important today, should be based on that principle.

In conclusion, it should be mentioned that basic principles of grape breeding were established and confirmed by the findings arising from the search of initial forms of grapevine and by the highlighted regularities governing the inheritance of resistance to pathogens in grapevine. Breeding for resistance to pathogens was viewed as a specific target without respect to other desired characteristics since this issue was tackled with an aim to determine breeding and genetic regularities of the process and, for the first time, in terms of the interaction of two biological objects, the host plant and the pathogen, each with its own variation and evolutionary patterns.

#### 5. Crossability of plants as a genetic determined sign

In this stage of scientific knowledge and expertise, the concept of evolutionary development of the flora on Earth is based on the existence of certain centers of origin of cultivated plant species, including grapes [24]. A fundamental contribution to the development of the theory of centers of origin was made by Vavilov [31]. Negrul has further developed this theory [32], highlighting the ecological and geographical areas forming the autochthonous grape varieties. These varieties form separate ecogeographical groups of autochthonous grape varieties. The "Black Sea" area is one of such ecogeographical zones, where autochthonous grape varieties are formed [33]. Within the bounds of this zone, modern scientists have identified specific subcenters of origin of the grapes, one of them being Crimea [21, 34], where relict endemic wild forest vines exist to date. This resulted in the formation of a specific set of autochthonous grape varieties with characteristic biological features in the Crimea, due to which they are used in the breeding programs developed by the "Magarach" Institute [3].

It should be noted that the process of breeding new varieties, as a rule, involves analysis of the combining ability of the initial forms with regard to the inheritance of the degree of trait expression in the progeny. At the same time, it has to be kept in mind that in the course of generative hybridization, the formation of a germ and seeds, along with hybridization efficiency, differs between various initial forms, and we can assume that this is a genetically predetermined feature. Therefore, the autochthonous grape varieties of the Crimea are characterized by specific crossability that has become part of their DNA in the process of natural evolution. The present work focuses on the analysis of this phenomenon.

It is known that the majority of the Crimean local grape varieties has a functionally female flower type and is, therefore, not resistant to the biotic and abiotic environmental factors. This affects the stability of fertilization and vine yielding capacity. It is possible to increase the adaptive capacity of the Crimean local grape varieties not only by the selection method but by the hybridization method as well. It is worthwhile to evaluate the hybridization efficiency of the Crimean autochthonous grape varieties, which, first and foremost, require determining the parameters, based on which such studies may be performed. The formation of a new genotype of a plant consists of two principal stages: (1) hybridization, to include formation of berries and seeds, and (2) the development of seedlings and of their vegetative propagation later on.

According to the earlier data, the berry formation in different breeding combinations is characterized by biological traits of the initial female plant, while it is not dependent on the male form, which has been supported by the number of berries per bunch of a cross-combination. Therefore, there is no need to consider the number of bunches and berries per bunch in the further study of grape crossing capacity. When assessing crossing capacity, it is more important to pay attention to the number of the formed seeds, including the fully formed ones, as compared to the number of berries with formed seeds, and to the number of seedlings obtained in the end of the process, including the vigorous ones.

The grape plant, as a biological object, exists and develops in the biosphere, being in permanent contact with and affected by biotic and abiotic factors. Careful consideration is given to the effects of biotic factors on development of a plant organism, including grapevine, due to the specific nature of the phenomenon, the essence of which lies in the fact that two biological objects, the host plant and the

The fact that variation of biological objects is governed by the abovementioned regularities enables evolutionary models to be built.

A number of regularities governing the expression of resistance to Plasmopara viticola, Uncinula necator, and Botrytis cinerea, the causing agents of mildew, oidium, and gray rot, respectively, and the inheritance of this characteristic in the F1 progeny were established in grapevine as a result of our long-term research aimed to breed for resistance of the crop to these fungal pathogens. The nature of the inheritance of resistance to these pathogens in grapevine seems to be identical despite the fact that they differ in biological characteristics and the form of hostpathogen relations.

8096 hybrid seeds were obtained as a result of the crosses. As can be seen from the data presented in Table 3, which characterize the extreme contrasts among the obtained results, the greatest number of seeds was formed in combinations with 'Muscat Jim' as female form, from 853 to 546 seeds, and the minimum number was formed in the combination of 'Krona' 'Krasen' (3 seeds).

On average, fully formed seeds accounted for 85%, while the number of fully formed seeds in 'Krona' variety in three cross-combinations reached up to 100%. Less than mean value, from 80 to 46% of fully formed seeds were formed in almost all backcrosses involving 'Kok Pandas' as the female form. Above-average percentage of fully formed seeds was observed in populations of 'Kefessia' 'Rubinovyi Magaracha' and 'Kefessia' 'Bastardo Magaraci', 97% and 98%, respectively. Seed germination analyses revealed the lowest percentage in cross-combinations of 'Kok Pandas' with 'Sauvignon vert' (32%), 'Chardonnay' (41%), and 'Rkatsiteli' (46%). Seed germination in combinations of 'Kok Pandas' with interspecific varieties of 'Aurora Magaracha' and 'Riesling Magaracha' made 60%. The maximum viability was observed in the seeds of 'Sary Pandas' variety in combinations with interspecific male forms of 'Citronnyi Magaracha' (82%) and 'Riesling Magaracha' (78%). A lower percentage of germination was observed in cross-combinations of 'Sary Pandas' 'Sauvignon vert' (76%) and 'Sary Pandas' 'Chardonnay' (73%). The average seed germination value for all the populations was rather high and reached up to 51.2%.

As a result, we were able to grow 4143 seedlings, out of which only 258 were vigorous (16.7%). Of particular interest in terms of this indicator was the combination of 'Krona' 'Alminskyi' (17%) and 'Krona' 'Rubinovyi Magaracha' (15%). Of similar powerful growth force were seedlings in the populations of Magarach № 31-77-10 'Gevat Kara' (14%) and Magarach № 31-77-10 'Kokur White' (13%). We were not able to single out any vigorous seedlings in combinations of 'Sary Pandas' 'Chardonnay', 'Sary Pandas' 'Pervenets Magaracha', 'Kok Pandas' 'Aurora Magaracha', 'Kok Pandas' 'Spartanets Magaracha', 'Kok Pandas' 'Citronnyi Magaracha', and 'Kok Pandas' 'Rkatsiteli'. The average number of vigorous seedlings in all populations was 6.2%.

The crossability efficiency of the grapes as to the formation of fully formed seeds and their germination capacity with the resulting vigorous seedlings is determined primarily by the use of a particular female form in a cross and its ripening period. In the present study all the female forms had an average ripening period, which provided a sufficiently high percentage of germination. To analyze the effect on the viability of the offspring, we took six initial female forms, which were cyclic crossed with male forms, and grouped them into unified complexes (Table 4). The number of seeds produced in these crosses fluctuated significantly from 484 seeds for 'Krona' to 2668 seeds for 'Kok Pandas'. The average sample value was 188.3 of hybrid seeds, while the coefficient of variation for the populations made 38 of seeds. At the same time, the percentage of fully formed seeds out of their total number in cross complexes fluctuated insignificantly, from 87.3% (for 'Sary Pandas') to 95.2% (for 'Kefessia'), with the exception of 'Kok Pandas', which showed 67.9%, as evidenced by the excess of the variation coefficient. The mean value for seed germination capacity in all the complexes made 58.9%. The greatest number of vigorous seedlings was observed in female forms of Magarach № 31-77-10 (13.5%), 'Krona' (10.2%), and 'Muscat Jim' (10%). 'Kok Pandas' produced the lowest percentage of vigorous seedlings that amounted to 1.1%. In all the populations, the vigor of seedling growth varied considerably, with its rate reaching up to 78.7%.

From the analysis of the obtained data, we may conclude that 'Krona' produced the least number of hybrid seeds that came up to 484, 10% of them produced vigorous seedlings, while 'Kok Pandas', although having formed the highest number Crossbreeding

The number of fully formed seeds out of their total amount was high enough and ranged from 69.5% for 'Pervenets Magaracha' to 95.3% for 'Riesling Magaracha'. The analyzed crosses were also characterized by a sufficiently high percentage of seedlings from fully formed seeds, which varied in the range from 56.0 to 63.3%, while all the indicators of seed germination were within the variation coefficient (13.1). The number of the obtained vigorous seedlings varied significantly (up to 83.6%). The greatest number of vigorous seedlings was produced from combinations with the following varieties—'Alminskyi' (11.0%), 'Podarok Magaracha' (10.0%), and 'Pamyati Golodrigi' (9.0%).

Assessing male forms as to the transfer of the powerful growth force feature to the offspring, it may be noted that the largest number of vigorous seedlings was obtained in combinations with 'Kokur Belyi' and 'Gevat Kara' (12.5%). The mean values, 7.7% for variations, were exceeded by 'Rubinovyi Magaracha' (10.0%) and 'Bastardo Magaraci' (8.5%). The smallest percentage of the vigorous seedlings was observed for 'Chardonnay' (3.0%).

By comparing the impact on crossability of the Crimean autochthonous grape varieties of different male forms represented by varieties of V. vinifera species and those of interspecific origin, it is possible to ascertain some consistent patterns.

The observed variation coefficients of crossability indicators as to the formation of hybrid seeds obtained from intraspecific crosses within the species of Vitis vinifera are almost twice lower than in interspecific crosses. The established mean value for cross-combinations of the fully formed seeds differs insignificantly among intraspecific (within the species of Vitis vinifera) and interspecific crosses, with difference between them of only 1.9%. The established average percentage of seed germination capacity has determined a higher viability of hybrid seeds obtained as a result of cross-species hybridization.

The analysis of the studied cross-combinations allowed concluding that as a result of crossings within the species of Vitis vinifera the mean value of the obtained vigorous seedlings was almost 1.5 times lower than in interspecific crosses.

Thus, we were able to establish the genetically determined specificity of the crossability of the Crimean autochthonous grape varieties. By all crossability indicators of the Crimean autochthonous grape varieties, the variability was lower within the species of Vitis vinifera than in the interspecific hybridization. Using autochthonous variety 'Krona', as a female form, and interspecific variety 'Alminskyi', as male form, proved most efficient for obtaining vigorous progeny.

#### 6. Modeling at plant breeding

In the middle of the twentieth century, there existed the so-called model of ideal variety of a grapevine—a concept that comprised the ultimate complex of the desired basic phenological and agrobiological characteristics in varieties that were to be cultivated on a vineyard [35]. But global and local climatic changes along with the change in biosphere conditions demanded creation of new cultivars, in particular in viticulture [36]. The global problem was not only to preserve the grapevine gene pool diversity but also to breed new grapevine cultivars that would correspond to modern conditions of biosphere [37].

Scientists in different countries discuss the problem and methods of creating a new genotype with given parameters [27], including the one on the basis of modeling [38]. A program for immunobreeding "Analogue" that is based on models of new grapevine cultivars was developed [39] and is being implemented at the "Magarach" Institute. The program aims to improve the efficiency of grape breeding and to achieve varieties, whose characteristics would be distinguished for genuine novelty. The breeding objective of the program is the development of new grape cultivars that would combine resistance to a variety of pests, diseases, and unfavorable environmental factors and would, at the same time, produce fruit of the quality comparable to the best samples of the existing international analogues. To achieve this, new baseline material is searched for, accumulated in collections, studied, and involved in generative hybridization.

In this study preference was given to the elongated oval-shaped berries. However, very early-ripening cultivars mainly produce a rounded berry. Apparently, this feature is associated with the biological specificity of the berry formation and the origin of table grapes Vitis vinifera orientalis Negr. that is related to soil and climatic conditions of their origin. Many varieties of eastern ecogeographical group, 'Husaine Kelim Barmak', 'Shami Abiad', 'Fakhri', and others, have an elongated oval or cylindrical berry shape and are characterized by the average ripening time. The main objective of a plant is to generate progeny and in the case of grapes to produce seeds. It is known that very early-ripening cultivars have zero seed germination due to the insufficient formation of a normally developed embryo and endosperm, while the seeds of the average ripening period cultivars have the highest viability. It is possible that the genetic correlation between the shape and weight of berries and the ripening period is due to the biological dependence of the length of the vegetation period and formation of a sufficient amount of biochemical compounds. However, the studied hybrid progeny has a high degree of heterozygosity. Initial forms of interspecific origin represent at least 5 generations and have more than 50 ancestors. The oval shape of a berry is intermediate between the round and cylindrical forms. Therefore, in the process of breeding early-ripening cultivars with oval berry shape, there is a sufficiently high degree of probability to obtain hybrids with this berry shape. The most valuable populations in this case were obtained by crossing with 'Flora' cultivar, specifically 40–43.9%, in the geno-

percentage of anthocyans (phenolic compounds) in the skin of the berries, the longer is the period during which they can be preserved. The economic value of this feature increases with the elongation of the vegetation period. Very early-ripening varieties do not require long-term storage, as fresh grapes are sold without storage and are in high demand. With the increase in the vegetation period, however, the potential yield of varieties increases, along with their competitiveness. Thus, it develops the need for a short-term storage of early varieties, smoothly developing into the long-term storage of late varieties. Therefore, the model of a table variety displays the optimal berry coloration resulting from the content of anthocyans (phenol compounds) and aroma compounds [30], associated with the ripening

As a result, the most effective crossbreeding combinations were identified with the purpose of obtaining model for early-ripening table cultivars.

Populations that include 'Talisman' variety show the highest breeding value of the inheritance of a big berry, reaching up to 100%. The high breeding value is due to the biological capacity of the 'Talisman' variety to generate a very big berry, the weight of which reaches up to 24 g, and a high degree of transmission of this trait to its progeny in populations.

Hereby, the overall combining ability of the 'Talisman' variety influence on the increase of the berry weight in progeny as compared to the average indices of the original forms happens with a fairly low severity of 1.25%.

Among a number of prerequisites necessary for the stable and efficient functioning of any crop production, a special place belongs to the sustainability of its development. This concept includes a whole range of organizational, economic, social, and environmental assessments. The most important of them for agricultural production is the requirement to adequately meet the needs of living people, without depriving this opportunity for future generations, the need to harmonize the way of life with the ecological capabilities of the region, and the introduction of certain restrictions on the exploitation of natural resources due to the ability of the biosphere to cope with the consequences of human activities. This is consistent with the international convention on the ecological status of the biosphere on the planet. Sustainable development is the main condition for the effective functioning of agricultural production. At the heart of sustainable development of agricultural production are several main factors. One of them is environmental conditions, the requirements for which are presented by living organisms—soil, plants, animals, birds, and insects—which are diverse due to the biological characteristics and diversity of living organisms themselves. The yield of crops and, as a consequence, the economic efficiency of production are determined by the extent to which the living conditions correspond to the requirements of the biology of living organisms. No other circumstances, the provision of machinery, pesticides, and fertilizers, although important, cannot replace this requirement. From this basic condition follows the main task for agriculture, which consists in creating in each soil climatic zone such biocenoses, whose biological requirements would be most adequate to the conditions of their functioning. Only in this case, it is possible to count on their optimum productivity. The main functional unit of the agricultural biocenosis is a variety. Naturally, in these conditions, it is necessary to pay priority attention to the use of biological reserves of the plants themselves of agricultural crops. In other words, it is necessary to go as far as possible toward the creation and use of new selection varieties of grapes that meet modern requirements of agricultural

technology and the conditions of the biosphere to the maximum.

93

This is also confirmed by the fact that in the complex of biological sciences that solve the tasks of increasing the productivity of agricultural production, the most solid positions belong to genetics. At the same time against the background of changing climatic conditions and an increase in the epiphytotic load of phytopathogens in agrocenoses, it becomes most expedient to use varieties of a new breeding generation and clones of traditional varieties resistant to biotic and abiotic factors.

of improving the methodology and scientific foundations of breeding genetic research, as well as increasing the efficiency of agricultural production only on the basis of the development and implementation of national programs. The leading role in the development of these programs should be carried out by the national scientific institutions of the country, to which the All-Russian National Research Institute of Viticulture and Winemaking "Magarach" belongs in Russia. At the present time, in the "Magarach" Institute has developed and is implementing a genetic selection program for the breeding of new grape varieties "Analogue." This program provides for the modeling of new grape genotypes based on the developed models. In turn, the formation of models of new varieties of grapes is based on established patterns of manifestation and inheritance of selectable features selected for each model according to breeding value, crossability, hypothetical heterosis, and

The analysis of the inheritance of the aggregate model features allowed creation of new table cultivars of very early-ripening period with big berries and bunches: 'Solnechnaya grozd' ('Flora' 'Find of Mariupol'), 'Liviya' ('Flamingo' 'Arcadia'), and 'Academician Avidzba' ('Present to Zaporozhye' 'Rishel'e').

The conducted research established global and local climate change and the associated change in the biotic stress factors of the biosphere. This problem results in a need to cultivate new grape cultivars that are environmentally plastic and resistant to the biotic and abiotic factors of the biosphere. The targeted creation of new grape cultivars based on formulation of models and their subsequent implementation is perceived as the most successful approach.

The hybridological analysis of the newly created grape hybrid gene pool revealed the most effective combinations of crosses for early-ripening cultivars with a big berry. Also, the general and specific combining ability for certain initial forms that appear in the progeny was identified. Overall, the model practice allowed obtaining new early-ripening grape cultivars with big berries that are being successfully cultivated in the vineyards under different environmental conditions.

#### 7. Aspects of the general and particular in the formation of programs of fundamental scientific research in horticulture

The modern conditions of the biosphere and the cultivation of agricultural crops, which include horticulture and grapes in particular, determine the need for the formation of scientific research programs, the implementation of which would improve the efficiency of agricultural production, in particular of these crops. The analysis of the complex of scientific researches makes it possible to note that genetic selection and physiological-biotechnological priorities can be considered as priority directions and effective implementation of specific scientific developments is possible only after taking into account the existing environmental factors of biotic and abiotic nature.

One of them is environmental conditions, the requirements for which are presented by living organisms—soil, plants, animals, birds, and insects—which are diverse due to the biological characteristics and diversity of living organisms themselves. The yield of crops and, as a consequence, the economic efficiency of production are determined by the extent to which the living conditions correspond to the requirements of the biology of living organisms. No other circumstances, the provision of machinery, pesticides, and fertilizers, although important, cannot replace this requirement. From this basic condition follows the main task for agriculture, which consists in creating in each soil climatic zone such biocenoses, whose biological requirements would be most adequate to the conditions of their functioning. Only in this case, it is possible to count on their optimum productivity. The main functional unit of the agricultural biocenosis is a variety. Naturally, in these conditions, it is necessary to pay priority attention to the use of biological reserves of the plants themselves of agricultural crops. In other words, it is necessary to go as far as possible toward the creation and use of new selection varieties of grapes that meet modern requirements of agricultural technology and the conditions of the biosphere to the maximum.

This is also confirmed by the fact that in the complex of biological sciences that solve the tasks of increasing the productivity of agricultural production, the most solid positions belong to genetics. At the same time against the background of changing climatic conditions and an increase in the epiphytotic load of phytopathogens in agrocenoses, it becomes most expedient to use varieties of a new breeding generation and clones of traditional varieties resistant to biotic and abiotic factors.

The hybridological analysis of the newly created grape hybrid gene pool revealed the most effective combinations of crosses for early-ripening cultivars with a big berry. Also, the general and specific combining ability for certain initial forms that appear in the progeny was identified. Overall, the model practice allowed obtaining new early-ripening grape cultivars with big berries that are being successfully

The modern conditions of the biosphere and the cultivation of agricultural crops,

which include horticulture and grapes in particular, determine the need for the formation of scientific research programs, the implementation of which would improve the efficiency of agricultural production, in particular of these crops. The analysis of the complex of scientific researches makes it possible to note that genetic selection and physiological-biotechnological priorities can be considered as priority directions and effective implementation of specific scientific developments is possible only after taking into account the existing environmental factors of biotic and

The conducted research established global and local climate change and the associated change in the biotic stress factors of the biosphere.

Increasing the efficiency of agricultural production, including horticulture crops and grapes, is really possible only on the basis of the large-scale use of modern scientific and technical developments. The increase in the level of scientific and technological achievements and their use will enable the most fully to realize the high biological potential of the plant and thereby increase the supply of food to the population. At the same time, the priority areas of research are the creation of a new generation of winter-hardy, immune, and productive varieties providing highquality agricultural products, which are the basis of adaptive horticulture growing.

The criteria for breeding new generations of varieties of horticulture crops can be based on the same principles used in breeding programs adopted for individual crops, particularly for grapes. Based on knowledge of the existence of separate centers of origin of cultures, the evolutionary variability of plants, and the coevolution of plants and pathogens, it is possible to select the necessary initial forms for generative hybridization, which currently remains the main method in breeding. It is also possible to use the laws of genetically determined patterns of crossing and inheritance of signs and characteristics in individual crops when selecting other horticulture crops. Improvement of the methodology of breeding for the purpose of breeding a variety with the necessary parameters is possible, in particular, based on the development and implementation of models of new varieties, which take into account the knowledge of general and private genetics.
