Abstract The studies on the comparative assessment of soybean varieties of Siberian breeding performed in 2017-2019 in the sub-taiga zone of the West Siberian region showed that the duration of the growing season of soybeans depended on the biological characteristics of the variety and weather conditions. SibNIIK 315 variety was characterized by the shortest growing season – 96 days, while Cheremshanka variety had the longest – 108 days. Sibiryachka and Eldorado soybean varieties were the second in terms of early ripening (102-103 days). In wet 2017 and 2018, the growing season of the studied varieties was delayed by 9-15 days compared to warm and drier 2019. The yield of soybean grain was influenced by the characteristics of the variety and weather. On average, for three years of study, the highest grain yield – 2.65 tons/ha was obtained from Sibiryachka variety. SibNIIK 315 took the second place in terms of yield. In terms of grain quality, Zolotistaya and SibNIIK 315 with protein content of 32.6 and 32.2%, respectively, were the best. The protein content of Sibiryachka variety was less – 31.5%, but higher compared to Eldorado and Cheremshanka varieties.
