The presented article discusses ways to solve a very important problem concerning both agricultural producers and the population of any country - the cultivation and production of a sufficient number of potato tubers. Modern varieties of potatoes cultivated in the fields of the Republic of Kazakhstan are capable of yielding marketable tubers of more than 100 c/ha, but they realize their biological potential under production conditions by 15-30% [12]. A long process of vegetative reproduction of a culture contributes to the progressive accumulation of viral, viroid, fungal, and bacterial pathogens in plants [2]. The most effective way to improve the health of seed material at present is to obtain a healthy material based on the method of micropropagation [2-3; 12]. Potato varieties resistant to late blight were experimentally identified: Tavria, Vostochny-1 and Sante, in addition, varieties Vostochny-1 and Sante showed resistance to the Y virus.
