Abstract. In the Russian Federation, barley is widespread and cultivated in all soil and climate zones. The purpose of the research is to determine the adaptability of Omsk varieties of filmy and naked barley on the basis of “grain yield”. Methods. The research was conducted from 2015 to 2019 in the conditions of the southern forest-steppe of Omsk. A detailed analysis of the adaptivity parameters is given: the coefficient of the index of environmental conditions, plasticity and stability according; multiplicative coefficient according; the ecovalent of plasticity according; homeostaticity and the stability index; breeding value; genotypic effect, the rate of reaction of varieties to the environmental conditions. Final adaptability of varieties is estimated by the sum of ranks obtained each grade of the studied parameters. Results. The results of the research showed that the most adaptive in the conditions of the southern forest-steppe zone of the Omsk region are double-row filmy lines Nutans 4883, Nutans 4812 and variety Omskiy 101 (the sum of ranks = 34...38); multilayered membranous – Omskiy 99 and Nutans 4883 (sum of ranks = 54 and 56); two-row hulless hulless cultivar Omskiy golozernyy 1 (sum of ranks = 82); multi-row hulless varieties Omskiy golozernyy 2, Omskiy golozernyy 4 (sum of ranks = 86 and 84). Scientific novelty consists in the study of 8 varieties and 5 new promising lines of filmy and naked groups of barley, selection of the Omsk agricultural research center. The most adaptive varieties and lines for the conditions of the southern forest-steppe of Western Siberia are identified, which are recommended for introduction into production and for further breeding work.

Keywords: barley, yield, plasticity, stability, intensity, homeostaticity, multiplicative coefficient, breeding value, rank.
