摘　　要：以6个含有一年生墨西哥大刍草血缘的自交系为被测系,采用NCⅡ遗传交配设计对6个含大刍草血缘的玉米自交系的配合力进行研究。结果表明:亲本98-3//(200B/大刍草)///98-3的单株产量GCA较高;单株产量SCA效应值最大的组合是绵714×M4,具有一定利用潜力;根据SCA效应及产量表现,将6个远缘杂交选系初步划分为4个不同类群。利用一年生墨西哥大刍草来改良普通栽培玉米自交系是可行的,但选到理想自交系的可能性较小。Objective： To study the combining ability of 6 maize inbred which derived from annual Mexican teos with the （ 200 B/ （ 200B/ of yield inte x Maize Inbred. Method： The experiment analyzed the combining ability of 6 maize inbred methods of NC II genetic crossing design. Results ： The highest GCA of yield parent was 98 - 3// teosinte）///98 -3 which have good yield potentiality. According to the special combining ability by Teosinte is available. But the possibility of getting the good inbred is very low.
