Abstract: One hundred and fifty-three crosses mated w ith Griff ing method by 18 widely used maize ( Zea mays L. ) inbred lines were evaluated at several locat ions in 1994, the grain yield combining ability including SCA and GCA w ere analyzed. Classif icat ion of inbred lines w ere made by using the datum of specific combining ability . 18 inbred lines w ere div ided into 10 g roups, they areⅠ( Lancaster ) : Mo17, Q i302;Ⅱ ( Shi Pingto) : Huang zao 4, Jing 7 huang , Yie 515;Ⅲ( Improved Reid) : Yie 8112, Zheng 32, Tie 7922, Shen 5003, Yie 478;Ⅳ( Luda Hong gu) : Dan 340, E28;Ⅴ:Zong 31; Ⅵ: Zi 330;Ⅶ : Yie 107;Ⅷ: Huo Bai; : Yie 52106; Ⅸ: Aijin 525. The analyzing method of combining ability and mutual effect with environment was introduced and the relationship between specific combining ability and genotypes of parent inbred lines was discussed.

Key words: Maize, Inbred line, Specific combining ability, Cluster analysis
