The urgency of this problem is explained by the fact that keela causes enormous damage to agricultural crops all over the world, and in particular to white cabbage. The most effective way to cope with the disease is to create genetically resistant varieties and hybrids. In representatives of B. oleracea, only polygenic recessive resistance was found. To create B. oleracea plants with monogenic dominant resistance to keel, it was proposed to transfer resistance genes from B.rapa plants with this type of resistance. For reliable resistance from different races, it has been established that it is necessary to combine several dominant resistance genes in one genotype, which we can identify using molecular markers.
