Fodder and seed productivity of the bonfire awnless of the selection of Omsk agrarian scientific center

The study was conducted in 2019–2023 in the Omsk region in order to assess the feed and seed productivity of varieties of bonfire awnless selected of the Omsk Agrarian Scientific Center and the selection of the most promising material from the studied material for further use in breeding work. The material was varieties SibNIISHoz-189 (standard), SibNIISHoz-88, Titan, SibNIISHoz-99, Elbrus and Effect. Three cycles were carried out: summer sowing in 2019, 2020 and 2021, accounting years, respectively, 2020–2021; 2021–2022 and 2022–2023. During the experiments, the yield of green mass and absolutely dry matter, seed productivity were evaluated, biochemical analyses of the green mass of varieties were carried out to determine the content of the mass fraction of protein and fiber. In all years of the research, during the growing season, increased air temperature was noted, exceeding the long-term average data by 1.6…1.8 ºС and a large deficit of precipitation. The GTC values by year were: 2020–0.60; 2021–0.56; 2022–1.02; 2023–0.85, with the optimal –1.13. On average, over 3 cycles of research, a significant excess over the standard was characterized by: in terms of green mass yield – varieties SibNIISKhoz-88 and SibNIISKhoz-99 (9.6 and 7.3 % of st.); in terms of absolutely dry matter yield – SibNIISKhoz-88, SibNIISKhoz-99, Titan and Effect (7.8…11.1 % to st.); in terms of seed yield – SibNIISKhoz-99, Elbrus, Effect and Titan (16.5…22.8 % to st.). The mass fraction of protein in the green mass of the Effect variety, on average, over 3 evaluation cycles significantly exceeded the standard by 0.8 %, while the fiber content was at the standard level.
