大豆杂交育种相像组配是通过创造各种具有某些特异性状或优良性状且遗传力强的相似群,在组配亲本时根据育种目标,从相似群中选取与核心亲本大部分性状相同、目的性状互补的材料为另一亲本进行杂交。这种方法可排除或减少非目的性状对目的型重组的干扰,提高选择率,增强定向性,使优良组合率由不到1%增加列13%和23%。优株率由5%左右增加到23.6%. Soybean crossbreeding similar grouping is through the creation of a variety of specific traits or with good traits and hereditary similar groups, according to breeding objectives in the group with the parent, selected from similar groups and the core of most of the same parents, the purpose Mutual traits hybridize to another parent. This method can eliminate or reduce the interference of non-target traits on the target type recombination, improve the selection rate and enhance the orientation, so that the excellent combination rate increases from less than 1% to 13% and 23%. The rate of excellent plants increased from 5% to 23.6%.
