Abstract

The work was carried out in 2019 in five ecological points of Kurgan region: at Kurgan Scientific Research Institute of Agriculture and at 4 state-owned sections (Belozerskiy, Polovinskiy, Kurtamyshskiy, Dalmatovskiy). The purpose of the research is to identify varieties with high productivity and ecological plasticity for use in crosses when creating new highly productive spring wheat varieties. We tested 26 varieties of various biotypes with a growing season from 70 (Novosibirskaya 16) to 92 (Lider 80) days. Plant height ranged from 65 to 110 cm. The best in yield in the early ripening group (29.5 ... 30.3 c/ha) were Omskaya 36, Tarskaya 12, Extra; mid-season (32.6 ... 32.9 kg/ha) - Heracles Icarus, Zauralskaya volna; medium-late (36.6 ... 37.4 kg / ha) - Bulyak, KVS Buran, KVS 240-3-13. Dusty smut (defeat 27 ... 30%) was observed in Silach, Raduga, KVS Torridon varieties. High resistance to stress (U2-U1 = -8.6 ... -11.6) was found in the genotypes Zauralochka, Tarskaya 12, Zauralskaya volna, low (-20.3 ... -28.0) Lider 80, Novosibirskaya 16, Bulyak. The most stable under changing growing conditions were Zauralochka variety samples (V = 11.8%; Hom = 29.4), Zauralskaya wave (V = 16.3%; Hom = 17.4), and Raduga (V = 16%; Hom = 17.7%). Low ductility at the level of bi = 0.31 ... 087 was recorded in the varieties Zauralochka, Novosibirskaya 16, Tarskaya 12, Omskaya 36, Boevchanka, Zauralskaya volna. Varieties KVS Torridon, Raduga, KVS Buran, KVS Jetstream, Krasnozerka, Zauralskaya zhemchuzhina, Lutetsiya, KVS 240-3-13 can be grown on an intensive background (σd2 = 0.6 ... 5.0). Raduga variety formed a consistently high productivity in different growing conditions. According to a set of indicators and related calculations, it is recommended to use the following varieties combining yield with ecological plasticity parameters for inclusion in the system of crosses: early ripening - Extra, Tarskaya 12; mid-season - Hercules, Icarus, Lutetsiya; medium-late - KVS 240-3-1, Bulyak, KVS Buran.
