In order to establish the influence of climatic conditions on the total antioxidants content (TAC) in the grain, oat samples were grown for three years in three geographical points of the Krasnoyarsk territory and the Republic of Khakassia: Krasnoturansky, Beisky and Shirinsky State Varietal Site (SVS). The research objects were 4 hulled and 1 naked sample oat: the Argument, Rovesnik (Selma), Sayan, Tubinskiy and Golets. To determine the TAC in the grain, 2 solvents were used - bidistilled water or 70% ethanol. The measurement was performed on the device «Color Yauza-01-AA». Gallic acid was used as a comparison sample. In parallel, the duration of the growing season and the production characteristics of oats: 1000 grain weight and the yield were measured. The extraction methods used showed almost the same results. It is shown that the levels of TAC in oat grain grown in different geographical locations for three years did not significantly differ from each other. There was no statistically proven correlation between the level of TAC in oat grain on the one hand and 1000 grain weight, the length of the growing season or the grain yield on the other. In this case, the presence of tendency of relationship between the level of TAC in the grain and the duration of the growing season (positive), and the grain yield (negative). It was found that when growing oats in different years, but in one geographical point, the level of TAC in all varieties changed the same type, and the ranking of samples on this basis was not violated. In the case of growing oats in different places, the value of TAC in all varieties changed disproportionately, and their ranking on this basis was noticeably violated. Naked oat sample compared to hulled not allocated by level TAC in the grain.
