Studies were carried out in Kirov (Federal Agricultural Research Center of the Northeast) and in Samara oblasts (Samara Agricultural Research Institute, Samara Federal Research Center, Russian Academy of Sciences) with the purpose to breed covered oat lines with enhanced grain yield, grain quality, and fodder productivity parameters in conditions of agroclimatic resource instability. Data collected in 2018–2020 made it possible to select 13 covered oat lines combining high yield capacity with other economically valuable traits, including promising line 325h12 featuring a high crop-yield capacity (6.94 t/ha in Kirov on an average) and high-quality grains (grain unit = 592 g/L, thousand grain weight = 39.9 g, husk content = 23.3%, protein content = 12.25%, and fat content = 6.2%) and line 178h13 intended both for grain production (crop yield = 5.15–7.69 t/ha) and fodder production (dry matter yield = up to 14.0 t/ha, protein content = 10.47%, fat content = 2.16%, and fiber content = 3.99%). Line 325h12 features a higher grain-yield capacity, while line 178h13 has a higher fodder productivity. The "year" factor affects the crop capacity greater (46.7%) than the "genotype" (11.1%) and "state of agroclimatic resources at the point of study" factors. In 2019, the yield capacity of line 325h12 in Kirov oblast was 8.31 t/ha, while it ranged from 6.78 t/ha in Kirov oblast to 3.25 t/ha in Samara oblast in 2020. [ABSTRACT FROM AUTHOR] |
