通过冬春性小麦杂交世代主要性状的配合力与杂种优势的研究表明:同一性状不同品种的一般配合力和特殊配合力相对效应存在较大的差异:特殊配合力效应值较高的组合,其杂种优势较强,杂种后代表现愈好,但还与亲本的一般配合力效应有关.因此在选择中必须注重亲本的一般配合力的选择.实践证明,京花2号和荆阿的殊特配合力效应虽表现稍差,但一般配合力效应较好,是两个具有较高利用价值的亲本.
The study on the combining ability and heterosis of the main characters of the winter and spring wheat crosses showed that there are great differences in the general combining ability and the special combining ability relative effects of different cultivars with the same trait. The combinations with higher specific combining ability Therefore, it is necessary to pay attention to the selection of the general combining ability of the parents in the selection.Practice has proved that the special combination of Jinghua No.2 and Jing A Although the effect of force is slightly worse, but the general effect of combining force is better, is the two parents with higher value.
