| 摘 要： | 以南21－3等7个玉米自交系为亲本，按照双列设计组配一套不包括反交的组合。对雄穗主轴长、雄穗分枝数、雄穗总分枝长进行配合力分析及相关研究。结果表明，3个雄穗性状的GCA、SCA效应及变异程度均存在显著差异；3个雄稳性状的GCA、SCA与其性状表现型值（X）存在显著或极显著正相关。除主轴长与分枝数的GCA外，3个雄穗性状的GCA和SCA之间具有极显著的相关关系。

| Abstract: | The comining ability and correlations of rnain axis length,branch num-ber and tota length of branch of maize tassel wee studied by Griffing 2 of diallel cross with 7 rnaize self - bred lines. The result indicated that there was a significant difference in the GCA, SCA effect and varance in all tassel characters, and that highly significant correlations between GCA and SCA of the three tassel charaters and their phenotyPe values were found, and that a significant correlation between GCA and SCA of the three tassel charaters was also found but the GCA correlation between main axis length and branch number. |
