The experiment was conducted in Summer-Autumn season of 2015 and 2016 in Thai Nguyen with 10 soybean varieties (DT84, DT2001, DT51, DT34, DT22, DT12, D8, DT2008, Cuc Bong, Vang Cao Bang). The goal was to select soybean varieties with good growth and high yield during the Summer-Autumn season in Thai Nguyen. The experiment was arranged according to Randimized Complete Block Design (RCBD) with 3 replicates, using variety DT84 as control. The results showed that, of the 10 soybean varieties tested, 2 varieties DT12 and D8 belonged to the group of early ripening (growth time <
85 days)
the rest of the varieties were in the medium ripening group (growth time from 86 - 101 days). The soybean varieties DT51, DT2001, DT2008 showed outstanding physiological indicators such as LAI index, number of nodules compared to the control variety and the remaining soybean varieties. The soybean variety DT51 selected by the Pea Research and Development Center showed its ability to grow and develop well in the Summer-Autumn season in Thai Nguyen, with an average yield of 25.13 quintals/ha, higher than the control DT84 (19.90 quintals / ha).Thí nghiệm được thực hiện vụ Hè Thu năm 2015 và 2016 tại Thái Nguyên với 10 giống đậu tương (DT84, DT2001, ĐT51, ĐT34, ĐT22, ĐT12, Đ8, DT2008, Cúc Bóng, Vàng Cao Bằng).
