Abstract: Five diallcl cross trails of corn and luccrn were made by using stable materials .to study their two kinds of combining abilities.The results indicated that all characters showed this tendency: GCA× E>SCA× E, except a lew characters, but SSs/(SSs+SSsc)< SSg/(SSg+SSge).It was explained that GCA was more stable than SCA in various environments.Because the ratio of interaction of the two combining abilities to the main effects showed a tendency of (SCA × E)/SCA>(GCA × E)/GCA, the GCA should be a center to be tested in various environments, but SCA should not be neglected in special environments.The interaction of GCA × E was mainly caused by the change of variance value in different environments, in essence, by the difference in effects of ecological factors to the characters.
