摘要
利用3个中国大豆品种和2个日本大豆品种杂交,对F2群体主要性状的平均值及遗传参数进行分析。结果表明,各性状的变异因亲本的不同有明显差异。对产量性状而言,利用日本10品种配制的组合F2变异幅度较小,而用日本9号品种配制的组合F2变异幅度大,有较广阔的选择基础。
Three Chinese soybean and two Japanese soybean varieties were crossed and parameters of main inheritable characters in F2 progeny were analyzed. Results shown that there were significant difference in variability of every character in progeny of different parents. Taking crop yield for instance, a little range of variance occurred in F2 progeny when'Japanese 10'was used as a parent, whereas a large range of variance occurred in F2 progeny when'Japanese 9'was used as a parent and the diversity made it easy to select an improved variety.
