The Study Results of Potato Growing Originated From Different Ecological and Geographical Zones Under Conditions of Krasnoyarsk Forest-Steppe

University, Krasnoyarsk, e-mail: khalipskiya@mail.ru The article reveals some issues related to the economic assessment of potato varieties, depending on the region of its origin. The research was carried out during 2016–2017 in the Krasnoyarsk region. The soil of the experimental plot is agricultural chernozem leached medium-power medium-humus heavy loamy. Eighteen varieties were studied, grouped by their ecological-geographical places of origin: Krasnoyarsk region, Kemerovo region, Western Siberia, the European part of russia, Germany, the Netherlands. in terms of the number of tubers in the bush, varieties of Pamyati rafiq (13 pcs., Krasnoyarsk region), Gala, arizona (14 pcs., Germany), Nevsky (15 pcs., the European part of russia) were selected, compared to the standard breeds: the mid-maturity Lina (12 pcs.), mid-season Tuleyevsky (8 pcs.). varieties of the Krasnoyarsk Territory (Krasnoyarsk Early, Pamyati rafiq), Kemerovo region (Tanai), Netherlands (arizona), Leningrad region (Nakra) shown the productivity of more than 1300 g per bush. The aramis, Tuleyevsky and arrow varieties had the highest average tuber weight. Large cultivars had less than 10 tubers in the clone. The varieties from the Krasnoyarsk region are on the first place by the crop-production power (48.4 t / ha), the second place took the varieties from the Kemerovo region (40.7 t / ha), and the third place took varieties from the Netherlands (39.8 t / ha). The starch content revealed a significant variation within the studied varieties. The minimum value of the indicator was recorded in the breeds arrow (10.2 %) and Colomba (10.6 %). These varieties can be recommended for diabetic nutrition. High starch content was found in the varieties Nakra (20.1 %) and Hozyaushka (20.9 %). it was established that the maximum profitability was obtained from varieties created in the
