Relevance Breeding for resistance is one of the priorities when working with late-ripening cabbage.The most significant damage to this crop in the south of Russia is caused by diseases such as fusarium, black rot, and from pests - tobacco trips. Methods The purpose of the research is development of heat-resistant hybrids of medium-late and late maturity of various areas of use with complex resistance. For 2 decades much attention was paid to breeding and immunological work on development of inbred lines with group resistance: to fusarium and polygenic resistance to black rot. The study of race-specific resistance for better protection against black rot began in 2013. At that, the progeny of the lines were eveluated, which were selected by hydathogenic polygenic resistance on the infectious background of cabbage during inoculation of plants with the Krasnodar population of the pathogen.Since specific resistance to a particular race inherited in white cabbage is recessive and it is very difficult to develop lines and hybrids resistant to several races, a strategy was chosen to increase resistance to this dangerous disease based on a combination of field resistance, stem resistance to the main race 1 and leaf resistance to one or two races...
