| 摘 要： | 利用9个玉米自交系，按 Griffing完全双列杂交方法4组配成36个杂交组合进行试验。对主要数量性状的一般配合力、特殊配合力、配合力总效应以及各自交系的特殊配合力方差进行估算和分析。结果表明，自交系411的一般配合力最高，自交系405和琼180具有较高的一般配合力和特殊配合力方差，其配制的组合配合力总效应高，系组配强优势杂交组合的优良自交系。

| Abstract: | In this paper,9 maize inbred lines used were crossed according to Griffing's method four,36 hybrids were got.Complete random block design was taken.Estimation and analysis on GCA,SCA,TCA of main quantitative characters and variance of SCA of every line The results showed that inbred line 411 had highest GCA,inbred line 405 and qiong 180 had higher GCA and variance of SCA Higher TCA on hybrids of these lines were crossed They were fine inbred line in hybrids were got. |
