Title: Study of Combining Ability of S-type Male Sterile Inbred Lines
Abstract: The combining ability and genetic parameter of8quantitative characters of the male sterile line ST039,ST029and the other5inbred lines were analysised by dialel cross method.And ST039,Dai20,ST029,and D15were ascertained to be good inbred lines that they had more usages according to the value of GCA and SCA,and the combination ST039×D15,Zong31×Dai20had higher heterosis than the others,and had good yield potential.Ac-cording to the combining ability and genetic parameters,GCA account for high genetic value than SCA,so we should select the inbred lines that had higher GCA value as parent when we shoose the combination,and also the GCA of special combination of special characters.
