Due to the changing climatic conditions in the Southern Federal District over the past thirty years, the yield of spring barley has fallen sharply due to the sharp hot and extreme temperatures. In 2023, based on early research and a summary of meteorological forecast data in the Volgograd region, an experiment was launched on the basis of the Federal Scientific Center of Agroecology of the Russian Academy of Sciences in Kamyshinsky district to test spring barley varieties: Medicum 139, Medicum 200, Kamyshinsky 23, Dmitrievsky 5 and Novonikolaevsky. These varieties were selected as the most stress-and drought-resistant in terms of their breeding characteristics.
The technology of cultivating varieties of spring barley in field experiments was according to B.A. Dospekhov and the methodology of the state variety testing of agricultural crops.
When studying the products of spring barley varieties, variety tests were conducted in arid conditions of the Southern Federal District. The study of the potential of spring barley varieties in experimental plots according to PP and NPP made it possible to assess the productivity of crops in the “germination-tillering” phase. The results of leaf diagnostics, further research in the Kamyshinsky district allowed us to identify the most heat- and drought-resistant varieties despite extreme weather conditions.
