ECONOMIC-BIOLOGICAL AND TECHNOLOGICAL ASSESSMENT OF PEA CULTIVARS AND LINES BRED BY THE BASHKIR RIAUFRC RAS

The purpose of research is to study the economic, biological and technological properties of pea variety samples selected by the Bashkir Research Institute of Agriculture UFRC RAS. The object of study is the varieties Chishminskiy 95, Chishminskiy 229, Pamyati Khangildina, Pamyati Popova, included in the State Register of Breeding Achievements of the Russian Federation, and breeding lines L-30, L-118, L-31045. The standard is the variety Aksayskiy usatyy 55. The experiments were carried out in 2020–2022 in the fields of the Chishminskiy plant breeding center. The evaluation of the studied variety samples was carried out in accordance with the methods of state variety testing. Grain yield was determined by the gravimetric method. Technological indicators of grain quality were assessed in the laboratory of selection and primary seed production of leguminous and cereal crops and in the analytical laboratory of the BRIA UFRC RAS. As a result of a comparative study, sources for a number of economically valuable traits were identified for use in breeding. Sources of early ripening can be the varieties Chishminskiy 95, Chishminskiy 229, Pamyati Khangildina, L-31045 with a growing season of 64–65 days, high grain yields – Chishminskiy 229, Pamyati Popova, L-30 (17.7–18.8 c/ha). As a source material with high technological indicators of grain quality, the varieties Chishminskiy 229, Pamyati Khangildina, L-30 with a weight of 1000 seeds over 190 g can be used; Chishminskiy 95, Chishminskiy 229, In Pamyati Khangildina, In Pamyati Popova, L-118, L-31045 with seed uniformity of 85.7–87.7 % and digestibility of 97.3–102.3 min; Chishminskiy 95, Pamyati Khangildina, Pamyati Popova, L-31045 with a grain yield of 83.1–84.2 %. Intervarietal coefficients of variation for the traits we studied were low, which is due to the genetic proximity of varieties and local breeding lines.
