| 摘 要： | 研究以灰色系统理论为依据,采用灰色关联度分析法,对玉米自交系组合的子粒产量与9个农艺性状的相关性状进行分析。研究结果表明:玉米杂交组合的产量是由多种因素控制的,农艺性状中影响产量的因素顺序为:抽丝期>百粒重>穗粗>株高>出籽率>穗行数>穗长。

| Abstract: | The grey related degree analysis was employed to investigate the relationship between the kernel yield of maize hybridized combination and eight main agronomic characters in this study.The result showed that the yield of maize hybridized combination was affected by multiple factors,and the affecting degree of agronomic character was as followings: silking time(X1) > 100 seeds weight(X8) > ear thickness(X6) > plant highness(X2) > kernel ratio(X4) > kernel line(X7) > ear location(X3) > ear length(X5). |
