选配亲本是小麦杂交育种成败的关键之一。实践经验表明:亲本的表现与杂交后代的表现并不一定完全一致;有些亲本品种本身表现很好,但所产生的后代并不理想,而有些亲本品种并不很突出,但杂交后代却表现优异,这就是亲本材料存在的配合力问题。所谓配合力,是指亲本材料在杂交后代中,所表现的将有利特性潜力传递给杂种后 Matching parents is one of the keys to wheat breeding success. Practical experience shows that the performance of the parents is not necessarily the same as that of the hybrid offspring. Some of the parent breeds perform well on their own, but the resulting offspring are not ideal, while some of the parental breeds are not prominent but the offspring of hybrids perform well. This is the problem of the combining ability of the parent material. The so-called combining ability, refers to the parent material in the hybrid offspring, the performance of the potential characteristics of the potential passed to the hybrid
