The efficiency of selection of resistant forms is 18.7%. Based on the results of the research, it was established that 11 hybrids were free from Y-virus, X-virus, and S-virus of potatoes. Among the 76 studied hybrids, 60 (79.4%) did not have the Y virus and 58 (76.5%) did not have the X virus.). 453 hybrids were evaluated for resistance to leaf blight, of which: 92 were resistant (20.3 The efficiency of selection of resistant forms among the studied breeding material was 20.3%. 469 hybrids were evaluated for resistance to alternariosis, of which: 74 (15.8%) were resistant. The efficiency of selection of resistant forms among the researched breeding material was 15.8%. 236 hybrids were studied for resistance to ring rot from them: high resistance was noted in 70 (29.7%) hybrids Efficiency of selection of resistant forms is 29.7%. 394 hybrids were evaluated for resistance to blackleg, of which: 126 were resistant (32.0 426 hybrids were studied for resistance to wet rot, of which: high resistance was noted in 77 (18.1%) ) of hybrids. Among the researched breeding material, the efficiency of selection of resistant hybrids was: 32.0% to black leg and 18.1% to wet rot. Five breeding samples were characterized by a combination of resistance to black leg and wet rot (7.7-8.0 points). 220 x hybrids were studied for resistance to stem nematode, 57 were resistant, 123 were moderately resistant, and 40 were susceptible. The above-mentioned hybrids and parental components, with the participation of which they were obtained, are recommended for inclusion in the selection process to create new varieties with increased resistance a leading feature.
