摘要： 运用灰色关联分析方法对13个饲用玉米品种生物学产量和籽粒产量与相关因素关系的研究分析，结果表明，饲用玉米生物学产量与主要性状间的关联度顺序为：株高>穗位高>成熟期保绿度>穗行数>行粒数>结实长>吐丝期>穗长>穗粗>籽粒产量>千粒重；籽粒产量与主要性状间的关联度顺序为：千粒重>穗长>结实长>行粒数>穗粗>行数>生物产量>株高>穗位高>成熟期保绿度>吐丝期。

Abstract: The grey related degree analysis was employed to investigate the relationship of biomass and some main characters of the thirsty forage maize varieties. The resucts showed that therelated degree order of biomass and main traits was plant high>ear high>being green to riping>row number>kernels per row>fertility length>silking stage>ear length>seed yield>weight per 1000 kernels；the related degree order of seed yield and the main trait was weight per 1000 kernels>ear length>fertility length>row number>ear diameter>kernels per row>biomass>plant high>ear high>being green to riping>silking stage.
