| 摘 要： | 用灰色关联度法分析了8个玉米品种淀粉含量和穗部性状的关系。结果表明，穗部各主要性状对淀粉含量的灰关联度顺序为：轴粗〉行粒数〉容重〉穗行数〉穗长〉穗粗〉出籽率〉百粒重，为普通玉米育种和高淀粉玉米育种提供了理论依据。

| Abstract: | The grey relational analysis was conducted to study the correlation of starch content and ear characters of 8 maize cultivars.The grey relational degree was in the order of axis diameter>kernels per row>gain unit weight>rows per ear>ear length>ear diameter>rate of kernel>100-kernel weight.This study was expected to provide a theoretical foundation to high-starch maize breeding. |
