摘要: 试验以4份玉米自交系与4个测验种(昌7-2、郑58、PH4CV、PH6WC)通过不完全双列试验,研究了7个产量性状的一般配合力(GCA)、特殊配合力(SCA)、遗传参数和GCA间的相互关系.结果表明:以C50-5-14为母本组配出的杂交后代产量高,株高适中,株型为紧凑型,利用前景较好,适合做一种良好的亲本.C50-5-14×PH4CV,C50-5-14×昌7-2、C50-5-14×郑58三个组合产量较高,且其单株产量的一般配合力和特殊配合力值均较其他组合高,即这3个组合具有增产表现,株高适中,易改良出好的品种.

Abstract: In this experiment,four maize inbred lines were crossed with four testers(chang7-2,zheng58,PH4CV and PH6WC).GCA (general combining ability),SCA (special combining ability) and population genetic parameters ,were investigated in 7 Characters of yield in maize. The results showed that the hybrids (one of parents was C50-5-14) were relatively easy access to high-yield combination, and proper plant height and shape. Three hybrid combinations (C50-5-14×PH4CV,C50-5-14×Chang7-2,C50-5- 14×Zheng 58) were of higher grain yield and smaller plant height,which could be improved good variety.
