Diseases are one of the reasons for the decline in yield of rape. Breeders are to create resistant to diseases and pests varieties and hybrids of rape because this culture is widely used in Russia. Nowadays we know about 30 pathogens of cabbage cultures. Among the diseases of rape are alternaria, fusarium, sclerotinia, powdery mildew, fomoz, perinospora, bacteriosis, etc., which cause a shortage of yield from 15 to 70%. Varieties of rape for resistance to alternaria, perinospora, and fusarium were appreciated at the All-Russian Scientific Research Institute of Rapeseed from 2016 to 2018. The most samples of Brassica napus were affected by alternaria in mild and moderate degrees. The degree of damage by perinospora depended on weather conditions and ranged from a very weak level to an average one. The degree of damage by fusarium was from single to weak and it was connected with many years of the research work. Thus, we could isolate samples, weakly susceptible to alternaria; samples, weakly susceptible to perinospora; samples, weakly affected by fusarium.
