| 摘 要： | 应用灰色关联分析法(gray correlation analysis),对10个宁夏玉米杂交种的7个数量性状与子粒产量进行分析,明确各数量性状与籽粒产量的关联度,结果表明,玉米杂交种各数量性状(quantitative trait)与产量的关联度大小顺序为:叶数>行粒数>株高>穗长>百粒重>穗行数。

Grey Correlation Degree Analysis on the Yield and the Yield Traits of Maize |
| |
| Abstract: | By using grey correlation analysis method,seven quantitative traits and the grain yield of 10 maize hybrids of Ningxia were analyzed.The correlation degree between each quantitative trait and the grain yield was confirmed.The results showed that the correlation degree between each quantitative trait of maize hybrids and the yield was as follows: leaf number>grain number per row>plant height>ear length>100-grain weight>ear row number. |
