摘　　要：应用灰色关联度分析方法,对2008～2012年利用PH6WC组配的入选杂交组合9个主要性状进行分析。结果表明,各性状与产量的关联度大小为百粒重>穗长>秃尖长度>穗位高>株高>穗行数>粒穗比>脱粒水分。不同年份由于气候不同,各性状与产量的关系有相应的变化。粒穗比、脱粒水分与产量关系不密切,粒穗比与脱粒水分关系不密切。Nine main traits of selected hybrid combinations in PH6WC were analyzed by the grey correlation analysis method in 2008-2012. The results showed that the correlation among the traits and yield was 100-kernel weight〉ear length〉bare top length〉ear height〉plant height〉rows per ear〉ratio of kernel and spike〉threshing moisture. Because the climate is different in different years, the relationship among the traits and yield had the corre-sponding changes. No close relationship between ratio of kernel and spike and yield, no close relationship between threshing moisture and yield, no close relationship between ratio of kernel and spike and threshing moisture.
