Abstract
Due to the increased interest in the cultivation and use of naked oats in recent years, the evaluation of naked samples of spring oats of competitive variety testing by grain yield and the elements of its structure was carried out. The studies were conducted in 2013-2021. Eleven naked spring oat samples of the "Nemchinovka" Federal Research Center selection were studied. The Tyumensky Golozerny variety was used as a standard. During the experiment, sample yields ranged from 1.9 to 2.9 t/ha. Four samples stood out in terms of yield: 52h2467 (2.9 t/ha), 38h2273, 11h2619 (2.5 t/ha each), and 2h2348 (2.3 t/ha). The increase to the standard variety in these samples was 0.1-0.7 t/ha with LSD05 = 0.13-0.53 t/ha. The maximum grain yield (32% more than the standard) in a competitive variety trial showed the sample 52h2467. During the 9 years of research the high-est yield was observed with productive bushiness 1.1-1.4 units, the weight of 1 thousand grains 30.2-35.2 g and the weight of grains per a panicle 0.90-2.06 g. According to the results of the correlation analysis, the productive bushiness (r = 0,72), the weight of grains per a panicle (r = 0,70) and the weight of 1 thousand grains (r = 0,38) are the main elements of the crop structure, which have the strongest impact on the yield of grain in the Northern region.
