Comparative assessment of the resistance of introduced spring oat varieties to arid climate of the Astrakhan region

In the semi-desert zone of the north of the Astrakhan region, a comparative assessment of spring oat varieties from the world collection of VIR was carried out. The 2019-2021 studies included 57 variety samples. Based on the results of the study, the most resistant samples were identified, capable of producing a stable crop, regardless of the climatic conditions of the current years. These samples are distinguished by: high field germination, early maturity, high levels of plant productivity elements, and, consequently, high genetic potential of variety samples. Selected varieties: Leo, Scorpion and Borets (Moscow region) with a yield of 3.48, 3.00   and 2.70 t/ha, respectively.
