| 摘 要： | 选用吉林农业大学育成的12份爆裂玉米自交系做杂交亲本,采用NCⅡ不完全双列杂交设计配制出32个杂交组合进行配合力测定和遗传参数分析。结果表明:吉B172、吉B166、吉B142、吉B140和吉B168是一般配合力(GCA)效应值表现优良的自交系;用其做亲本配制出特殊配合力(SCA)效应值高的组合吉B166×吉B140、吉B168×吉B151、吉B172×吉B129、吉B168×吉B140等。爆花率、膨爆倍数、穗位、百粒重、株高性状主要受加性基因效应控制,能够较稳定遗传;而穗行数、穗粗、穗长、小区产量性状等主要受非加性基因效应控制,受环境影响较大。

| Abstract: | By using 12 inbred lines of maize,32 crossing combinations were made according to incomplete dialed cross.Combining ability and hereditary parameter of 10 characters were analyzed.The results showed that inbred lines of ’JiB172’,’JiB166’,’JiB142’,’JiB140’ and ’JiB168’ had the higher general combining ability.Crossing combinations with high SCA included JiB166 × JiB140,JiB168×JiB151,JiB172× JiB129,JiB168×JiB140.Popping rate,expansion volume,ear height,100-kernel weight and plant height were controlled mainly by the additive gene,and they could be inherit stably.Ear length,ear diameter,row number of ear and grain yield were controlled mainly by non-additive gene.They could be influenced greatly by the external environment. |
