摘　　要：以8个ALEXHO高油玉米自交系为父本,21个普通玉米自交系为母本,采用NCⅡ遗传设计组配168个F1组合为供试材料,对其子粒油分、蛋白质和淀粉含量进行配合力分析。结果表明:除高油玉米自交系淀粉含量的一般配合力(GCA)方差以及淀粉含量的特殊配合力(SCA)方差不显著外,其余性状的GCA和SCA方差均存在极显著差异。GY220、GY246A、GY798A、P138、许178、8622油分含量的GCA较高,GY1007、GY237A、8085泰、沈137、改3、鲁原92蛋白质含量的GCA较高。P138×GY798A、87-1×GY246A、许178×GY798A和87-1×GY220组合油分含量高,鲁原92×GY1007蛋白质含量较高。Using 21 normal maize inbred lines as male parent and 8 ALEXHO high-oil maize inbred lines as female parent, 168 F1 crosses were made by NC Ⅱ genetic design. Combining ability of grain oil content, protein content and starch content were analyzed. The results indicated that GCA of the two kinds of parents and their SCA for most characters were significantly different except the GCA of high-oil inbred lines and the SCA for starch content. The GCA of GY220, GY246A, GY798A, P138, Xu178, 8622 for oil content and GY1007, GY237A, 8085tai, Shen137, Gai3, Luyuan92 for protein content were higher than others. The crosses P138 × GY798A, 87-1 × GY246A, Xu178 × GY798A and 87-1 × GY220 for oil content and Luyuan92 × GY1007 for protein content were higher than others.
