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。
The results showed that the inheritance of 17 plant type traits was mainly controlled by additive gene effect, and some traits were also affected by non-additive gene effect . GCA and SCA effects and their degree of variation of different plant type traits were significantly different; GCA and SCA of most plant type traits had significant or highly significant positive correlation with their phenotypic value (X), while GCA and SCA had no correlation There were significant or extremely significant correlations between GCA and SCA in some plant-type traits. There was no correlation between GCA and SCA in most plant-type traits.
