The purpose of the research: a comprehensive assessment of 43 genotypes of potatoes of domestic selection according to the main economically valuable characteristics in order to identify promising varieties for introduction into production. The experimental work was carried out in 2019–2021 at the scientific breeding and seed-growing center in the field of potato growing of the Ural Research Institute of Agricultural Sciences – a branch of the Federal State Budgetary Research University of the Russian Academy of Sciences (Yekaterinburg), as part of the scientific and technical program on the assignment of exploratory scientific research within the framework of the comprehensive research plan «Development of potato breeding and seed production». According to the methodology, phenological observations were carried out for each variety, the resistance of potato varieties to diseases and pests was studied, according to the results of dynamic digging, biometric indicators of plants (number of stems and height, weight of tops) and the accumulation of early potato productivity were analyzed. The varieties of the EGT nursery were evaluated by productive indicators (precocity, yield, marketability of tubers, number and mass of tubers per bush by fractions), in comparison with standard varieties – Red skarlett (early), Gala (mid-early) by dynamic trial digging 60 days after planting and during harvesting. Russian varieties with yields at the level of the Gala standard and above are highlighted: Debyut, Legenda, Grand, Korchma, Sadon, Alyaska, Kumach, Varyag, Krasa Meshchery. On average, over three years of research on the basis of precocity, varieties capable of forming yields from 18.0 to 24.5 t/ha 60 days after planting were identified: Legenda (24,5 t/ha), Debyut (19,3 t/ha), Sadon (19,0 t/ha), Plamya (18,6 t/ha), Kumach (18,5 t/ha), Serdolik (18,2 t/ha), Signal (18,0 t/ha); potato varieties are distinguished on the basis of high yield: Legenda (44,3 t/ha), Sadon (42,6 t/ha), Debyut (42,5 t/ha), Grand (42,2 t/ha), Alyaska (41,8 t/ha), Kumach (41,2 t/ha), Terra (40,7 t/ha), Korchma (40,5 t/ha), which are recommended for introduction into production to farms of all forms of ownership.

Key words: variety, testing, productivity, yield.
