Wintering oats in the conditions of the Maykop experimental station of RCRI

The article describes working with wintering oats at the Maykop Experimental Station. The authors analyze a fragment of the oats working collection of the FSBSI «Federal Research Center All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov (RCRI)», which remains alive in the Maykop district of the Republic of Adygea, consisting of 800 samples. The data on the distribution of oat samples by origin, species composition and varieties are presented. The second part of the article describes the study of samples of new arrivals in the RCRI collection in order to highlight promising material for solving urgent selection problems. The study consists of phenological and morphological observations, counts, assessment of resistance to biotic and abiotic factors, laboratory analysis of sheaf material. Productivity has been highlighted in the research, as the most important characteristic of a crop and a variety. For wintering oats productivity is closely related to overwintering conditions. Generalized data on overwintering of oats are presented and the causes of death of the samples are indicated. 448 samples from 46 countries have been studied for 10 years, 48 sources of high oat productivity have been identified, which we recommend for use in breeding
