| 摘 要： | 对应用温带骨干自交系和西南地方种质选育的15份玉米自交系,按GriffingD4模型进行双列杂交,组成105个杂交组合。采用完全随机区组设计进行试验,分析了生育期、株高、穗位高、穗长、秃尖、穗粗、穗行数、行粒数、千粒重和单株产量10个性状的GCA、SCA、TCA以及各自交系的SCA方差进行估算和分析。结果表明：各自交系的GCA、SCA方差均达到极显著水平。W 17,W 16,W 18,6-25,W 14这5个自交系综合性状表现突出,是组配强优杂交组合的优良自交系。

| Abstract: | 15 maize inbred lines（from Northeast and Huang huai hai region） used were crossed according to Griffing s method four,105 single crosses were got completed random block design taken,analyzing ten character GCA,SCA,TCA which are plant height,ear position,ear length,ear rows,and so on,and estimated each inbred line s SCA.The result showed that all inbred lines had remarkable variance of GCA,SCA.Comprehensive characters of inbred-line W17,W16,W18,6-25,W14 were outstanding and those were an excellent maize inbred lines on how to cross. |
