The method of artificial infestation of tubers was determined by the resistance against wet rot of 566 hybrids (76 resistant genotypes were identified), 192 specimens of fusariosis (25 isolates isolated), 256 samples of tuberous tuberophytes (high-altitude 32). The method of artificial infestation of leaves was determined by the resistance to fitolofois of leaves of 1100 hybrids (identified 93 persistent). On a natural infectious background, 673 hybrids were studied for resistance to alternaria (67 isolates were selected). Allocated hybrids as sources of resistance will be involved in the selection process for the creation of resistant varieties of diseases. According to the results of the research, a field method of testing varieties and breeding material for resistance to wet bacterial rot, a laboratory method for determining the presence of bacterial infection in a latent form, laboratory methods for determining the stability of selection material against leaf lettuce, alternaria and dry fusarium rot was developed.
