摘　　要：利用国内不同玉米(Zea mays L.)杂种优势群的5份代表自交系与来自CIMMYT的6份自交系,按不完全双列杂交组配30个杂交组合,分析了6个自交系7个穗部性状的一般配合力、特殊配合力和总配合力。结果表明,CIMBL98、GEMS13两份自交系性状综合表现较优,是组配强优势组合的优良自交系,CIMBL98×340、GEMS13×昌7-2是较好的杂交模式。Using 6 maize inbred lines from CIMMYT and 5 representative domestic maize inbred lines from different heterotic groups as parental lines,56 cross combinations were made with incomplete diallel design.GCA,SCA,TCA of 7 ear traits were analyzed.The results showed that GCA and SCA had better performance in many traits of CIMBL98 and GEMS13.CIMBL98×340 and GEMS13×Chang 7-2 were good combinations.
