摘　　要：以矮秆玉米自交系08H67-2为母本,以穗部性状差异比较大的30个自交系为父本进行杂交,通过对杂交后代F1的穗长、穗粗、穗行数、行粒数和出籽率等产量性状进行系统研究,从而分析08H67-2穗部性状的一般配合力。结果表明,以矮秆玉米自交系08H67-2为亲本组配杂交种时,其对杂交种穗部性状的一般配合力从大到小为:穗粗>产量>穗行数>穗长>行粒数>出籽率。了解其遗传特性,可为有目的地利用该自交系组配杂交组合和以其为基础材料选育新的自交系提供依据,以提高选育效率。Hybridizations using dwarf maize inbred lines ＂08H67-2＂ as female maternal line and 30 maize inbred lines as male maternal lines which had large ear type differences were made to analyse the general combining ability of ＂08H67-2＂ ear traits, by studying ear length and diameter, rows per ear, kernels per row and kernel percentage of F1. The results showed that the general combining ability of ＂08H67-2＂ ear traits from high to low was： ear diameter, corn yield, rows per ear, ear length, kernels per row, and kernel percentage. The result can provide a basis for the selective breeding of the new inbred lines with the aim of tissue culture and selection of new inbred lines, and can improre selection efficiency.
