Rapeseed (Brassica napus L.) is one of the most important oilseed crops worldwide, widely cultivated for the production of oil, protein, and various industrial purposes. Its taxonomy and distribution are of great significance for breeding, conservation of genetic resources, and adaptation to climate change.

The success of breeding work is determined by a wide range of source material, research areas, and breeding methods. The main method of breeding is interspecific hybridization followed by selection. Through crossbreeding, it is possible to recombine the traits and characteristics of the crossed genotypes in a single organism, discard the undesirable ones, select the positive ones, and create genotypes with new traits and characteristics.

Sometimes, as a result of crossing, with complementary gene interaction, new traits and properties arise that radically distinguish the hybrid organism from the original parental forms.

The possibility of obtaining new organisms capable of combining and developing the valuable properties and traits of the parental forms, as well as forming new qualities, has made the method of hybridization important in solving the problems of artificial directed form formation.
