| 摘 要： | 为了探讨玉米杂交组合产量与其他主要农艺性状间关联的主次关系,应用灰色关联度分析法研究13个玉米杂交新组合8个农艺性状对产量的影响及各性状间的相互关系,结果表明与产量的关联度大小依次为单穗粒重株高穗位高穗行数百粒重秃尖生育期穗长,在育种实践中,应注重对单穗粒重、株高和穗位高的选择,同时结合其余农艺性状的综合表现进行育种,将对产量有一个比较大的提升。

| Abstract: | The aim was to study the primary and secondary relations between the yield and the other main agronomic traits of maize hybrids. In this paper, the grey correlative degree analysis was used to research the effects of eight agronomic traits on yield of 13 maize hybrids and the relationships among those traits. The results showed that the values of the correlation degree between yield and main agronomic traits among different varieties were sequenced as follows: net weight per ear>plant height>ear height> ear row number> KWEI> bare tip length>growth period> ear length. In the breeding practice, it should pay attention to net weight per ear, plant height and ear height, and give dual attention to other agronomic traits, which was an effective way to enhance the maize yield. |
