| 摘 要： | 应用灰色关联度分析方法，对2010年参加辽宁省中熟玉米区域试验的10个玉米杂交组合的8个主要农艺性状进行分析。结果表明：各性状与产量的关联度大小排序为：百粒重、行粒数、出籽率、空秆率、穗长、秃尖长、穗粗和倒折率。百粒重、行粒数、出籽率、空秆率、穗长等因素与产量的关联度较高，对产量影响较大。百粒重和行粒数是辽宁省中熟玉米杂交种选育的主要影响因素。在选育中熟玉米品种时，应在保证适当百粒重和果穗长度的前提下，注重选育出籽率高，空秆率低的品种。

| Abstract: | The influence of nine main agronomic characters on yield of 9 new varieties and CK in the corn regional test in Liaoning in 2010 was analyzed with gray-relation analysis.The results showed that the magnitude on effects of vary characters on the yield in turn was 100-kernels weight,kernels per row,ear yield rate,barrenness rate and ear length.100-kernels weight and kernels per row were the key factor that change the yield of maize hybrid.It indicated that in the course of maize breeding,we should pay attenti... |
