Abstract
The combining ability for main quantitative characters of 14 maize inbred lines and 24 combinations were analysed in P1譖2 incomplete diallel crossing design,and 5 excellent inbred lines and 6 strong superiority combinations were selected from them.The results of combining ability in genotypic variance and hereditary estimation showed that additive variance of most characters were higher than their dominant variance,heritability of general combining ability was higher than that of special combining ability,so inbred lines which had high general combining ability should be selected as parent materials.
