摘要: 采用灰色关联度分析法对品种的小区产量与玉米株型性状、产量性状因素进行了关联度分析,结果表明:产量与各性状因素关联次序为:叶间距﹥行粒数﹥株高﹥单株穗粒重﹥茎粗﹥穗粗﹥穗长﹥穗位﹥叶片数﹥雄穗分枝数﹥茎叶夹角﹥叶面积﹥秃尖﹥穗行数。产量性状各因素与株型性状各因素的关联度分析中关联序各不相同,表现为复杂的关联关系。

Abstract: The grey related degree analysis was employed to investigate the relationship between plot yield with corn type traits and yield traits.the results showed that: the relative order of yield and characteristics factor was leaf spacing kernel per row grains plant height grain weight per plant stem diameter ear diameter ear length ear height leaf number tassel branch number Leaf angle leaf area bare tip length ear row number;The correlative order between Yield traits factors with type traits various factors was defferent and the correlation was complex.
