玉米淀粉含量和性状的关联度分析

Analysis of Grey Relational Degree on Starch Content of Maize and Their Characters

用灰色关联度分析方法,分析了玉米淀粉含量和性状的关系,并排出顺序:穗粗>穗长>百粒重>株高>产量>容重>生育期>穗位高,以期为普通玉米育种和高淀粉玉米育种提供理论依据。

The grey relational degree between starch content and characters in maize was analyzed in and ranged from maximum to minimum by the final results.The grey relational degree order is ranged from to minimum： ear wide 〉ear length 〉100-kernel weight 〉plant height 〉yield 〉grain unit weight 〉growth ear position. This study will be expected a theoretical foundation to high-starch maize breeding.
