It’s shown that it’s possible to apply selection as an independent method in naked oats hybridization. The variety of naked oats ‘Vyatsky’ was hybridized by the independent method together with negative rejection of hull. The variety ‘Vyatsky’ grown on the variety plots in Kirov region exceeded the standard of productivity on 0,66 t/ha in average. It produced a higher weight of grain 618-647 g/l, mass of 1000 seeds till 30,1 g, with protein content of 16,71% and fat content of 4,38%. The productivity of the variety on the plots in Yaran was 4,65 t/ha, exceeding the standard on 1,35 t/ha. Due to the participation of hulled oats ‘Ulov’ in hybridization the variety ‘Persheron’ was cultivated. Methodology of the variety ‘Persheron’ cultivation includes hybridization of naked and hulled parent forms, further choice on nakedness, field and laboratory rejections on hull. The new variety possesses high productivity (5,3-6,0 t/ha), mass of 1000 seeds (26-29 g), protein (16,58%) and fat (5,62%) content, and grain volume of 642 g/l. the same methodology is efficient for hulled oats cultivation. The study of inheritance of nakedness by the hybrids received from crossbreeding of the naked variety ‘Torch’ with five hulled genotypes shows the difficulty in selection of constant naked oats either in direct or indirect combinations of hulled and naked genotypes. Hybridization of constant hulled varieties from the given hybrids is efficient and accumulation of hulled forms occurs more often than that of naked ones. It’s shown that if own breeding material participates in hybridization as female forms, it gives a high percentage of seed setting (till 52,9-56,7 and 71,9%)
