In 2018-2020, Phoma rot (Leptosphaeria maculans Ces. & De Not) in the form of stem canker was the most common disease on winter rapeseed and winter brown mustard in the central zone of the Krasnodar region of the Russian Federation. Given the high prevalence and development of the disease in all years of research, we identified the rapeseed samples resistant to it; they had the affection degree of 1-2 points (9.0-12.0% of the total number of studied samples). The rest of the samples were weakly resistant with the affection degree of 3-4 points (33.0-39.0 % of samples), weakly susceptible with the affection degree of 5-6 points (28.0-40.0 % of samples) and susceptible with the affection degree of 7-9 points (15 0-23.0 % of samples). We also identified the samples resistant to Phoma rot during the examination of mustard. Their number was lower than that of the rapeseed – 3.0-6.0 % of the total number of samples. The main part of the samples was weakly resistant with the affection degree of 3-4 points (47.0-63.0 % of the total number of samples). The rest of the samples during the years of research were weakly susceptible with the affection degree of 5-6 points (11.0-30.0 %) and susceptible (9.0-18.0 %). The parental material of winter rapeseed and winter brown mustard, resistant to disease, can be used as the donors of resistance to Phoma rot in breeding work during the development of the new promising varieties.
