摘　　要：应用灰色关联度分析法,对19个玉米杂交组合性状进行分析。结果表明,各性状与产量的关联度大小依次为:株高>生育期>倒折率>穗行>行粒>秃尖>含水量>百粒重>穗位高>倒伏率>穗长>出籽率>穗粗。在育种工作中应该注重对株高、生育期和倒折率的选择,同时要结合不同性状间相互关系的综合表现进行育种,使玉米产量有较大提升。Grey correlation analysis was used to analyze the traits of 19 maize hybrid combinations.Results showed that the degree of association between various traits and yield was as follows plant height>growth period>the inverted folding rate>head progeny row>line of grain>bald tip>water content>hundred kernel weight>ear height>lodging rate>ear length>seed yield>spike thick.In the breeding work,we should pay attention to the selection of plant height,growth period and the inverted folding rate,and combined the comprehensive performance of the relationship between different characters to carry out the breeding,so that the yield of maize could be greatly increased.
