Abstract. The study aimed to identify soybean lines with high seed yield, high accumulation, optimal growing season, and suitable for mechanized harvesting. The experiments were conducted in 2017–2019 in the forest-steppe of the Middle Volga region. We compared seven soybean lines bred in the Samara Research Institute of Agriculture in collaboration with the Ershov Experimental Station of Irrigated Agriculture with the standard variety Samer 3. The soil of the experimental plot was ordinary heavy loamy chernozem. Meteorological conditions during the years of the study were contrasting in terms of moisture supply and temperature conditions. The year of 2017 turned out to be less favourable – the average yield of lines was 1.8 t/ha; the weather conditions in 2018 was average and the average yield of lines was 2.1 t/ha; in 2019 we registered high yield – 2.8 t/ha. Lines L 312 and L 319 were distinguished by a complex of economically valuable traits. They were characterized by high seed yields of 2.39 t/ha and 2.47 t/ha that was higher by 18% and 22% than that of the standard, respectively. The mass of 1000 seeds in these lines was medium (137– 144 g) and exceeded the standard by 12–19 g. The mass of seeds per plant in line L 312 was 4.7 g; in line L 319 it was 4.4 g; protein yield per 1 ha of the area under crop was 0.89 t/ha and 0.87 t/ha, respectively, while the value of this indicator for Samer 3 standard was 0.76 t/ha. The growing season of the best lines did not exceed 99–101 days, which was enough for growing them in all agroclimatic zones of the Samara region. The plants of the indicated lines proved to be highly suitable for mechanized harvesting – they did not lodge; they ripened simultaneously; the height of the attachment of the first bean was 14.4–16.2 cm.
Keywords: soybean (Glycine max (L.) Merril); yield; line; protein; suitability for harvesting; adaptability.
