摘　　要：文章应用灰色关联分析方法,对20个玉米单交种的8个产量基本性状进行了分析,探讨各性状与单株产量的关系。结果表明,关联度大小为百粒重>穗粒数>行粒数>穗粗>穗长>穗行数>出籽率>秃尖。说明在本生态区玉米育种和高产栽培的主要手段在于有效地提高百粒重,增加穗粒数和行粒数等因子,育种上可以把长穗型和大粒型作为高产品种的选择指标。This article used The Grey Relations Analysis analysised eight basic yield characters of twenty maize hybirds and disscussed the relations between the individual plant yield and other traits. The results indicated that the order of the relation from big to small was hundred-grain weight,the number of kernel per ear, the number of kernel per line, spike diameter, spike length,the kernel row number, the seeding rate, glabrate end. The conclusion expiousured the main way of maize breeding and high yield cuhurs on this ecological area is to raise hundred-grain weight, the number of kernel per ear and the number of kernel per line and so on other facters. The long spike varieties and big kernel varieties can take as the selection criterion of the high yield varieties.
