Analysis of variance for combining ability revealed that variances due to gca and sca were significant for all the traits except for TSS that exhibited non-significant mean squares for gca and sca in environment E1 only suggesting the importance of both types of variances in the inheritance of the traits. GCA and SCA also interacted significantly with the environments. The estimates of dominance variance were higher in magnitude than corresponding estimates of additive variance indicating the preponderance of non-additive gene action. |
