摘　　要：1980 ～1997 年山东省玉米主要种质中,BSSS 系统系呈明显上升的趋势,兰卡斯特系统系呈逐渐下降趋势,塘4 平头和旅大红骨子系统系呈波浪式变化。90 年代,BSSS 系统系占43-3 % ,塘4 平头系统系占30-0 % ,兰卡斯特系统系占10-0 % ,旅大红骨子系统系占6-7 % ,四大系统系共占90-0 % 。山东省玉米种质划分为五大杂种优势群,即兰卡斯特( 主要含Oh 43 亚群和C103 亚群) 、BSSS( 主要含8112 亚群和XL80 亚群) 、塘4 平头、旅大红骨子和其它种质杂种优势群,总结探索出10 种主体杂交优势利用模式和19 种子模式,其中,利用最多的子模式有3 种:8112 亚群×塘4 平头群、XL80 亚群×塘4 平头群和C103 亚群×塘4 平头群。The proportions of BSSS in maize main germplasms commercially used in Shandong province trended to increase obviously during 1980～1997,while main germplasms commercially used in Shandong province trended to increase obviously during 1980～1997,while that of Lancaster trended to decrease successively,that of Tang sipingtou and Ludahonggu changed.In 1990s,the components were;BSSS(43.3%),Tang sipingtou(30.0%),Lancaster(10.0%),Ludahonggu(6.7%),and the four core gerrmplasms had been up to 90.0%. The maize germplasms in Shandong province were divided into five heterosis groups,Lancaster(Oh43 and C103 subgroup),BSSS(8112 subgroup and others. This study also proposed ten main models,nineteen sub-models of maize heterosis utilizetion in Shandong province,three sub-models are widely used. 8221subgroup×Tang sipingtou group XL80 subgroup×Tang sipingtou group C103 subgroup×Tang sipingtou group
