Abstract: Our work is aimed at creating varieties of spring oats (Avena sativa), resistant to extreme conditions of the subarctic zone. The purpose of the research is to study and identify promising samples of oats with a set of positive features for breeding for high productivity, with high adaptation to biotic and abiotic stresses, in a competitive nursery for further breeding work. In the laboratory of plant of the Research Institute of Agriculture in 2016–2018 was conducted comprehensive assessment of the 46 samples in the conditions of European North of Russia. The article presents the results of eight released in the test samples: H-2446, H-2492, H-2502, H-2571, H-2555, H-2531, H-2629, 11H-2492. The yield of promising samples averaged 3.7 t/ha for 3 years, which compared to the „Chernigovsky 83“ standard was 128 %. The paper presents the results of the study of the elements of the structure of the crop of eight productive samples, the features of variation of the most important signs of grain yield in terms of three years, a significant correlation between the productivity and weight of 1000 grains (r = 0.62), the aver- age degree of relationship between the yield of grain and productive tillage (r = 0.40), the mass of grain from the main panicle (r = 0.3).
