摘要
对１７个株型性状的配合力及其与穗粒性状配合力的相关研究结果表明：１７个株型性状的遗传主要受加性基因效应的控制，部分性状同时受非加性基因效应的影响。不同株型性状的ＧＣＡ，ＳＣＡ效应及其变异程度均存在显著差异；大多数株型性状的ＧＣＡ，ＳＣＡ与其性状表现型值（Ｘ）存在显著或极显著的正相关，而ＧＣＡ与ＳＣＡ无相关；部分株型性状的ＧＣＡ和ＳＣＡ之间具有显著或极显著的相关关系；多数株型性状与穗粒性状的ＧＣＡ和ＳＣＡ之间不相关。
Study on the combining ability of the 17 plant characters and their correlationswith ear一kernal characters on combining ability indicated that the inheritance of all theplant characters was mainly controlled by additive gene effect,some were affected by non一additive effect simultaneously,and the GCA and SCA on most plant characters were pos-itively correlated with their performance(X),but the correlations between GCA and SCAwere not significant.There existed significant or very significant correlation between GCAand SCA in some plant characters. There was no correlation between GCA or SCA amongmost plant and ear-kerral characters.
