Introduction. Oats is a widespread forage crop. In areas with a complex nature of climatic conditions, not only increasing the yield of the crop, but also the issues of its stability is of particular importance. Therefore, the creation of highly adaptive varieties that can form high and stable yields of high-quality oat grain in different growing conditions is relevant and timely. The purpose of our research is to evaluate promising oat varieties in terms of yield and adaptability parameters on the basis of the results of their agroecological testing on arid agricultural lands of the Northern Caspian region. Materials and methods of research. The objects of the study were 7 varieties of oats of domestic selection (Kuryanin, Bulanyi, Lev, Arman, Urman, Pokrov, Assol), as a standard – the zoned variety Konkur. Varieties were tested in 2016–2018. Observations and accountings were carried out in accordance with generally accepted methods. Agricultural technology is generally accepted for the conditions of the North of the Astrakhan region. The results of the study, discussion. According to the results of three-year studies, the highest grain yield showed varieties Lev, Assol and Urman – 0.94 t/ha, 1.21 t/ha and 1.33 t/ha, respectively. Varieties of Urman, Assol, and Arman were distinguished by a complex of economically valuable traits, whose grains varied from 10 to 15 pieces, and the grain weight per panicle was 0.52 g, 0.32 g, and 0.31 g, respectively. Urman and Assol varieties had the highest mass index of 1000 seeds – 33.6 g. and 33.1 g, respectively. Conclusion. The highest level of adaptive capacity was shown by varieties Lev, Urman and Assol with an adaptability coefficient above one (1.1 to 1.4).
