Relevance. Potato hybrids obtained when creating varieties adapted to the weather conditions of the Komi Republic must have maximum resistance to constantly changing environmental conditions while maintaining the yield indicator at a high level. In addition, breeders impose requirements for their high field resistance to the main diseases common in the region: late blight, alternaria, rhizoctonia, scab and viruses (X, Y). In 2020, in the course of a continuously operating selection process, produced on the basis of the Institute of Agrobiotechnology FRC Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences (Syktyvkar) together with the FRC potato named after A.G. Lorkh (Korenevo), samples were taken from the nursery of the main test of hybrids.Methods. The studies were carried out on five hybrids sent from the FRC of Potato named after A.G. Lorkh obtained by hybridization of the original parental forms, growing hybrid seedlings and single-root hybrids, followed by selection in nurseries of single-root hybrids, second-year hybrids, preliminary and main tests already directly at the Institute of Agrobiotechnology FRC of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences. Observations, counts and culling in each nursery were carried out in accordance with the methodological recommendations on the technology of the potato breeding process. According to the research results, the hybrids were assessed in terms of yield, yield range (the difference between the maximum and minimum values for the study period), realization of yield potential (the ratio of the average yield to the maximum over the years of research) and coefficient of variation, as well as disease resistance.Results. As a result of a comprehensive assessment of potato samples in the nursery of the main test, three promising hybrids were identified — 1992–14, 2000–60 and 2139– 5 with an average yield at the level of standard varieties and higher (23.6–31.2t/ha), having a high stability and disease resistance.

In the Republic of Komi (Russia), one of the main agricultural vegetable crops cultivated by agro-enterprises, peasant farms and the population in the private sector is potatoes. The food security of Russia in the Arctic zone and obtaining competitive varieties for the regions of the Far North of our country is the main task solved by agricultural science in the field of breeding. New, promising varieties of potatoes must meet modern requirements for high yields obtained in various natural, soil and climatic conditions of their cultivation. In addition, varieties should have high stability in terms of commercial and economic characteristics and give an equivalent yield in constantly changing environmental conditions, both for the better (favorable) and for the worse (unfavorable). The use of modern methods of mathematical, statistical analysis, calculation of the assessment of environmental stability, plasticity, adaptability, as well as an objective and complete assessment of the potential of potato genomes, rigorous selection of promising lines and hybrids and screening for various negative traits, especially at the first stages of breeding, variety samples that do not correspond and do not satisfy these parameters, allow you to quickly obtain new varieties adapted to the Arctic zone of the Russian Federation. In order to strengthen breeding work aimed at breeding promising varieties of potatoes, in 2020-2022, a research program was carried out in breeding nurseries of the dynamic competitive first, second and third years of testing (hybrids of the sixth, seventh and eighth tuber generation) on the basis of the Institute of Agricultural Biotechnology of the Federal Research Center Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences (Russia, Syktyvkar). New promising potato hybrids (varieties) were selected as the object of study: 2341-265 (Amur x Gala), 2339-8 (Oksania x Gala), 2339-9 (Oksania x Gala), 1992-14 (Udacha x Elmundo), 2000-60 (Colette x FZ 1867); the standards were zoned and recommended for this region varieties of two groups of ripeness: Udacha - early, early ripening, Nevsky - medium early. As a result of research work in the course of a comprehensive assessment of ecological plasticity and stability, a promising potato hybrid 2000-60 was identified. This hybrid is characterized by stability to growing conditions,responsiveness to improved cultivation conditions, high average yield (33.7 t/ha).

Potato varieties with a complex of economically valuable traits, such as high yield, quality, disease resistance, are the key to successful competitive production in the Komi Republic (Russia). Agribusiness is increasingly demanding high field resistance of varieties to the main diseases and pests common in the region - viruses (X, Y), nematodes, etc. The Institute of agrobiotechnology of the Federal Research Center of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences (Russia, Syktyvkar) together with the FRC of Potato named after A. G. Lorkh (Russia, Lyubertsy) continuously conducts the process of obtaining new varieties of potatoes that are adaptive to the soil and climatic conditions of the North of Russia, having high field resistance to phytopathogens. A promising potato hybrid 2000-60, characterized by a complex of resistance genes to the golden potato nematode H1 (TG-689, 57R, N195) and potato cancer NL25 (Sen1), was isolated in the course of a comprehensive assessment of potatoes using the methods of molecular genetic analysis of gene markers. Based on the molecular genetic analysis of potato genes, hybrids 2339-8 and 1992-14 are recommended for crossing and obtaining new breeding lines in order to develop new potato varieties resistant to various types of nematodes.
