摘要
黑龙江省近20年来早熟大豆品种遗传改进的明显趋势是三四粒荚数、单株荚数、单株粒重、株高、分枝数和有效节数增多,底荚高度降低,单株粒数、每荚粒数、百粒重和蛋白质含量呈现先增后减的趋势,脂肪含量呈现先减后增的趋势。
The genetic improvement tendency of main agronomic characters of early - maturity soybean varieties developed by Heilongjiang in the last 20 years showed that pods with 3,4 seeds, pods per plant, seed weight per plant, plant heigh, number of branches and effective nodes tended to increase obviously, whereas bottom pod height decreased. Seeds per plant, seeds per pod, 100 -seed weight and protein content increased in early years and decreased in later years. In contrast, oil content tended to decrease in early years and increase in later years.
