Abstract. The purpose of the research was to investigate the effectiveness of the necrotic protective barrier in creating resistance to the Colorado beetle in potatoes. Methods. The research was carried out in a field experiment according to the accepted methodology for 3 years. The research involved 30 different potato varieties grown in conditions of the Cis-Ural forest-steppe of the Bashkortostan Republic. The analysis was focused on the correlation between the leaf blade hypersensitive response intensity on the Colorado potato beetle egg clutch on the one hand, and the level of plant resistance to the pest and loss of tuber yield from damage by parasite on the other side. Results. There was observed a strong association between the resistance of potato tops and the plant yield (the correlation coefficient is 0.763–0.804) when potatoes are grown without the control of the phytophage number. When growing potato varieties with insecticide application, the productivity of plants practically did not depend on their resistance level to phytophage. There has been found a strong positive correlation between the hypersensitive reaction of the leaf blades to Colorado beetle egg disposition and the resistance of different potato varieties to the pest (correlation coefficient 0.568–0.671). On the contrary, the relationship between the hypersensitive response of the leaf blades to the egg clutch and the decrease in yields was negative (correlation coefficient –0.646...–0.763). Based on the analysis of the obtained data, it is concluded that the stability of potatoes and the reduced loss of tuber yields from pest damage are closely related to the potato leaf response against the Colorado beetle clutch. The use of a necrotic protective barrier is a promising direction in breeding potato varieties resistant to the Colorado potato beetle. The scientific novelty lies in the study of the possible application of a new type of resistance and creating on this basis potato tolerance donors against the Colorado beetle.

Keywords: potato breeding, Colorado potato beetle, hypersensitive response.
