FIELD: agriculture.
SUBSTANCE: invention relates to the field of agricultural biotechnology, seed breeding of potato, potato farming. The method comprises culturing of sanitated potato plants in vitro by grafting on a nutrient medium containing macro- and microelements according to Murashige-Skoog, sucrose, Fe-chelate, glycerol, indole acetic acid, agar-agar, vitamins according to White, obtaining meristematic regenerated plants and planting the plants in soil. Before planting in the soil the meristematic regenerated plants are subjected to daily effect of temperature +4-+5°C for 2 hours during 6-7 days.
EFFECT: method enables to improve viability of the regenerated plants when transplanting into the soil, to increase cold resistance of potato plants by 55% and plant resistance to potato cyst-forming nematodes by 53%, and also to increase yield of potatoes.
