Аннотация: The study perpersents the influence of electron irradiation on on the phenology and productivity of potatoes inhabited by the fungus Rhizoctonia solani Kuhn. Potato samples were irradiated with the doses ranging from 0.02 kGy to 3.0 kGy. It was found that the pre-planting irradiation of seed potato tubers with the doses of 0.02-0.15 kGy led to a delay in plant development, and irradiation of tubers with over 0.2 kGy resulted in the death of plants. The maximum number of large tubers was obtained from samples irradiated with the dose of 0.15 kGy. The yield of potato tuber samples irradiated with the dose of 0.02 kGy corresponded to that of the control samples. Irradiation of potato seed tubers with a dose of 0.04 kGy led to a significant decrease in the colonization of the surface of tubers of the new crop with Rhizoctonia solani, while irradiation of potato tubers with a dose of 0.15 kGy completely eliminated the pathogen.
