摘　　要：对小麦杂交组合选配策略进行了探讨。认为:小麦杂交双亲均应具有较高的产量水平和较好的适应性,主要优点多且能互补;双亲要有一定程度的性状差异和中等大小的遗传距离;双亲在一般配合力高的基础上,特殊配合力要大;要重视具有亲缘或地理近缘关系双亲的利用。The strategies of wheat cross combination and assortative mating were discussed in this paper.The points were that the parents of wheat cross combination should both have higher yield and better adaptability,and the major advantages should be more and complementary; the parents should have character differences in some degree and medium sized genetic distance; specific combining ability should be big on the basis of higher general combining ability; more attention should be paid to the utilization of parents with genetic relationship or geographical relationship.
