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。
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.
