摘要
对大豆3个不同亲本类型的杂交组合 F_2群体主要性状遗传变异系数、遗传力和遗传进度进行了估算分析,结果表明:这些遗传参数因性状或亲本类型的不同而有明显差异。含有野生亲缘关系的组合,类型间、性状间 F_2遗传力有较大差异,性状变异幅度增大,相对遗传进度也较大,从而有较广泛的选择基础。
The results of analysis on genetic parameters(genetic varitation coefficents,hereditary capacities and genetic advances) of F_2 in three different soybean cross combinations showed that these genetic parameters varied significantly among the three types.The parameters in the parent forms with wild relatives have broader diversity for selection.
