| 摘 要： | 运用灰色关联度分析方法,研究了不同中晚熟玉米品种的农艺性状和产量的关系。结果表明这些品种中对产量影响最大的因素是倒伏率,其次是穗位,其他农艺性状对产量影响较小,秃尖长和穗粗对产量的的影响最小,其关联度仅为0.261 3和0.208 1。

Study on the Relationship Between Agronomic Characters and Yield of Different Corn Cultivar |
| |
| Abstract: | The relationship between agronomic characters and yield of different mid-late corn cultivar was studied by applying the method of grey correlated grade.Results showed that the most important agronomic character was lodging rate,the second was height from ground to ear,the others agronomic characters had less effect on yield. The bald tip length and ear thickness had the least effect on yield,the grey correlated grade of the bald tip length and ear thickness were only 0.261 3 and 0.208 1. |
