应用灰色理论关联度分析法,对在丽江参试的12个玉米新品系的9个数量性状进行分析。结果表明:丽江玉米产量是由多种因素控制的,产量与各产量性状的关联度大小顺序为单穗粒重>株高>穗粗>穗长>百粒重>行粒数>生育期>出籽率>穗行数。
By using gray theory correlation analysis method, 9 quantitative traits of 12 new maize lines tested in Lijiang were analyzed. The results showed that the yield of maize in Lijiang was controlled by many factors, and the order of the correlation between grain yield and yield traits was: grain weight per plant> plant height> ear diameter> ear length> grain weight> grain number> growth period> Seedling rate> number of ears.
