As well as the method of artificial infection of potato leaves with pathogens of late blight and Alternaria, allocated, respectively, 17 and 14 resistant breeding numbers for these diseases. There are 11 selection numbers resistant to the pathogen of wrinkled mosaic. By the method of artificial infection of tubers of newly created potato breeding material with the causative agent of dry fusarium rot, 5 hybrids with relative resistance to the pathogen were isolated, which will be used as donors of the trait, when creating fusarium resistant varieties of potatoes.
