本研究供试材料为从600多份苏浙春大豆地方品种中抽取的随机样本,1984年50个,1985年56个品种。两年试验均在本校江浦试验站进行。采用3次重复的随机区组设计,5行区,每行长2m,行距0.45m,株距0.1m。1.苏浙春大豆地方品种群体蛋白质含量、油分含量和产量的遗传变异 苏浙春大豆地方品种间6个性状两年均有极显著差异(表1)。该群体蛋白质含量较高,1984年平均45.7％,1985年44.8％。油分含量中等,1984年平均20.9％,1985年21.3％,两年 The test materials for this study were random samples from over 600 soybean varieties from Jiangsu, Zhejiang and Zhejiang provinces, 50 in 1984 and 56 in 1985. Two years of tests are conducted in our school Jiangpu Experimental Station. Three replicates of randomized block design were used. In the 5-row area, the length of each row was 2m, the row spacing was 0.45m, and the spacing was 0.1m. 1. The genetic variation of protein content, oil content and yield of soybean cultivars in Jiangsu, Zhejiang and Zhejiang Provinces There were extremely significant differences in six traits among the cultivars of soybean in Jiangsu, Zhejiang and Zhejiang Provinces for two years (Table 1). The group of high protein content, an average of 45.7% in 1984, 44.8% in 1985. Medium oil content, an average of 20.9% in 1984, 21.3% in 1985, two years
