摘要
研究了大豆荚粒性状的遗传变异度,验证了从引进品种(系)中进行系统选育的效果;测定了荚粒性状之间的遗传相关,为进行间接选育适应青海省地方品种积累科学资料;寻求比进行直接产量选育具有更高效率的选择指数。结果证明高寒地区进行大豆系统选育是行之有效的。
Soybean G-max breeds are abundant in our country and they are important original materials of selecting and breeding appropriate soybean breeds in high and cold area . In order to make good use of these resource, this paper will discuss: The heredity and verify the effect of going on systematic selection and cultivation from introduced breeds; Deterring genetic correlation between pods and seeds character so that some scientific data of indirectly selecting regional breeds which adapt to Qinghai province are accumulated; Seeking selection index which is more effective than direct output selection.
