摘　　要：以来自法国的6份玉米自交系为母本,以黑龙江省5个常用骨干自交系为父本,按不完全双列杂交组配30个杂交组合。采用完全随机区组设计,分析了株高、穗位高、穗长、穗粗、穗行数、行粒数、百粒重、出籽率、单株产量9个性状的一般配合力和特殊配合力。结果表明:自交系F43、F49和F51的一般配合力高,可直接利用;自交系F46、F55直接组配利用价值不大,但可用于改良低优势类群自交系的某些性状。Six maize self-bred lines from France were crossed as female parents with five local normal maize self-bred lines as male parents by using incomplete dual cross.The common combining ability and special combining ability of plant height,ear height,ear length,ear diameter,rows per ear,kernels per row,100-grain weight,produced kernel rate and yield per plant were analyzed.The results indicated that the lines of F43,F49 and F51 with the higher common combining ability could be directly used,the lines of F46 and F55 had no direct utilization value in cross making.But they might be used to improve the lines from their relative low heterotic groups.
