高寒地区大豆主要经济性状遗传相关和选择指数的研究

The study on Genetic Correlation and Selection Index of Soybeans Main Economic Character in High and Cold Area

为了有效地利用我国丰富的大豆品种资源,选育适宜高寒地区栽培的大豆品种。本文研讨:大豆荚粒性状的遗传变异度,以验证从引进品种(系)中进行系统选育的效果;测定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 variation level of soybeans pods and seeds character is studied test 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.
