**4. Conclusions**

Polyembryony in citrus is complex and affected by genetic, physiological, and environmental factors. Therefore, a better understanding of the development of the embryos in the seed requires further studies. We propose combining complementary techniques to molecular markers to identify the sexual or asexual origin, the individual follow-up of each embryo in the seed, and the subsequent evaluation of morphological and production characteristics of the plant. This process in citrus requires approximately 3 and 4 years to start fruiting. However, it is necessary to answer a few questions: If a seedling identified with molecular markers as "different or possibly zygotic" (with similarity indices less than 0.95) expresses these polymorphisms phenotypically? Do the embryos, based on their size and position in mature seeds, tend to be nucellar or possibly zygotic? Is it convenient to continue considering the percentage of polyembryony in citrus as a form of clonal propagation in nurseries? Are the plants obtained from the larger embryo asexual? These and so many more questions need further research.
