摘　　要：根据配合力、杂种优势、系谱关系、生理和遗传特点及形态特征等，结合育种实践，将我国玉米种质分为改良Ｒｅｉｄ、Ｌａｎｃａｓｔｅｒ（Ｍｏ１７和自３３０两个亚群）、四平头、旅大红骨和其它（外杂选、综合品种选、Ｓｕｗａｎ和低纬度种质４个亚群）５个杂种优势群９个亚群，提出了若干改良利用意见。并对种质基础狭窄、杂优群划分与利用、种质改良等问题进行了讨论。According to the combining ability,heterosis,pedigree relations and morphological,physiological and genetic characteristics,as well as the practice of breeding,the maize germplasm of China were divided into five heterosis groups and nine sub groups,i.e.improved Reid,Lancaster (Mo17 and Zi 330 sub groups),Sipingtou,Ludahonggu and others (subgroups such as:germplasms from foreign hybrids;selected germplasms,Suwan germplasm and other low latitude germplasm).The limited availability of germplasm,the division and utilization of heterosis groups,and the improvement of germplasm were discussed.
