Abstract. The studies aimed to determine the adaptive potential of common winter wheat varieties developed at the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences, when grown in the forest-steppe zone of the Ob region. The study material was 10 varieties of winter wheat (Novosibirskaya 32, Novosibirskaya 40, Novosibirskaya 51, Novosibirskaya 2, Novosibirskaya 3, Obskaya Ozimaya, Krasnoobskaya 27, Krasnoobskaya Ozimaya, Pamyati Chekurova, and Pisarevskaya). The experiments were performed in 2015–2020. The seeds were sown after the fallow forecrop on plots with a counting area of ​​16 m2 four times. The seeding rate was 6.0 million viable seeds per hectare; the sowing period lasted from August 25 to August 27. The best conditions were registered in 2017, when the average yield of varieties was 5.88 t/ha and winter hardiness was 72.2%. In 2016 and 2020 winter hardiness was below 50%; the average yield of varieties was 2.81 t/ha and 3.14 t/ha, respectively. The highest grain yield per unit area was observed in the varieties developed with the participation of hexaploid triticales: Krasnoobskaya Ozimaya, Pamyati Chekurova, and Pisarevskaya. In the experiment, the increase against the average yield varied from 0.52 t/ha to 0.90 t/ha. Varieties Pisarevskaya (V = 11%) and Novosibirskaya 3 (V = 23%) were classified as broadly adaptive, stable in yield and most adapted to changes in environmental conditions. Krasnoobskaya winter variety (bi = 1.22) was characterized as highly plastic with a high multiyear yield (3.14–6.73 t/ha). Varieties Novosibirskaya 40 (bi = 0.84, sigmad2 = 5.2) and Novosibirskaya 51 (bi = 1.02, sigmad2 = 3.3) were ecologically stable, not highly, but stably productive. High stress resistance was noted in Pisarevskaya variety (Ymin–Ymax = -1.42).

Keywords: winter common wheat (Triticum aestivum L.); variety; productivity; adaptability; stress resistance.
