**3. Prevalence**

Different parts of our planet have different types of climates. Climate conditions in a particular area can determine the productivity of crops or even the ability to survive. Similarly to other crops, the prevalence of oilseed rape mainly depends on climatic conditions. It is widely cultivated in many places in the world. However, the length of the growing season is slightly variable in different climate zones. It is one of the few suitable oilseeds in the temperate zone. It grows well in relatively low temperatures, with less heat required for successful reproduction than other oilseed crops.

Moreover, the global geographical distribution of both winter and spring oilseed rape botanical forms also depends on the climatic conditions (**Figure 2**). Due to the fact that winter oilseed rape form requires the vernalisation to start the flowering process, its cultivation mostly dominates in Europe (EU countries, UK and Ukraine) and Asia. Spring oilseed rape varieties do not require vernalisation and are widely cultivated in the northern part of America, Europe, and Australia [3, 10, 15].

The global oilseed rape market consists of separate geographical segments: North America (United States, Canada, Mexico), Europe (Germany, France, Italy, Russia, United Kingdom, Spain), Asia-Pacific (China, India, Japan, Australia), Middle-East and Africa (United Arab Emirates, South Africa). Many of the world's oilseed rape market belongs to North America, the EU, and China. The major oilseed rape producers in North America are Canada, the USA, and Mexico. Oilseed rape grown in France, Germany and the United Kingdom comprises a more significant part (more than 80%) of European oilseed rape production [10, 16].

The studies show that oilseed rape production areas have been steadily growing with the increasing global demand for food, feed, fuel, and industrial applications. The need for oilseed rape production encourages farmers to expand their planted areas of oilseed rape. The global production of vegetable oils is expected to increase by 79–100% by 2050 [16–18].
