Abstract. The purpose is to evaluate collection samples of oats for wintering resistance and grain yield in order to include them in the breeding process in the conditions of the southern foothill zone of the North-West Caucasus. Methods. The studies were conducted from 2020 to 2023 at the Research Institute of Agriculture of the Maikop State Technological University. The objects of the research were 188 collection samples of VIR (All-Union Research Institute of Plant Breeding) oats of various ecological and geographical origins. Mezmay wintering oat variety was used as a standard. The assessment was carried out in the field against a natural background. Observations and records of the main economically valuable traits were carried out in accordance with the Methodological Guidelines for the Study and Preservation of the World Collection of Barley and Oats. Results. The collection of oats from the Federal Research Center “All-Russian Institute of Genetic Resources named after N. I. Vavilov” (VIR) is a fundamental basis for breeding work and allows us to accelerate the creation of new varieties of wintering oats adapted to local soil and climatic conditions. As a result of the research, 5 sources of wintering resistance and 3 sources of grain yield were identified. Collection samples of Bond oats (cat. 8607, the USA), Texas 65C-306 (cat. 14973, the USA) can be used in crossbreeding to increase winter resistance and grain yield. The correlation (r) between grain yield and wintering resistance was average in all years of the research: 2020–2021 – 0.31, 2021– 2022. – 0.40, 2022–2023 – 0.51. Scientific novelty. A three-year assessment of 188 collection samples of oats has been carried out for wintering resistance and grain yield, sources of economically valuable traits identified that are of great interest for the creation of new original source material of wintering oats of hybrid origin. An average positive relationship has been revealed between grain yield and overwintering resistance of collection samples. Works has been carried out to preserve the genetic diversity of collection samples of oats with low resistance to wintering.
