| 摘 要： | 利用10份玉米自交系按不完全双列杂交配成25个组合,对其主要数量性状的GCA、SCA和遗传变量进行估算和分析.结果表明,除穗位高、千粒重、出籽率和子粒产量的SCA外,其余各性状的GCA和SCA都达到显著或极显著差异.H504、同系和82-2A等3个自交系综合性状较优,可组配强优势杂交组合的优良自交系。

| Abstract: | By using 10 inbred lines of maize,25 crossing combinations were made according to incomplete diallel cross,Analysising on GCA SCA and hereditary paramters of quantitanive characters.The results indicated that GCA and SCA of every character were significant except SCA of ear height,thousand kernel weight,product kernel rate and production.H504,Tong Xi and 82-2A were better,they were fine inberd lines. |
