Abstract

Ten maize inbred lines were used in a(5×5) incomplete diallel cross experiment,and general combining ability(GCA) and special combining ability(SCA) were analysised.The result showed that the inbred lines which have higher GCA should be used as the parents of combinations,at same time pay more attention to SCA,so that the combinations of strong heterosis were crossed.
