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. None of the parents exhibited desirable gca effects for all the traits simultaneously. The overall ranking of genotypes revealed that the parents Pusa Purple Long, GBL-1, Arka Nidhi, SBW-11, Pusa Purple Cluster and Local Long exhibited significant desirable gca effects for most of the traits. None of the crosses exhibited significant desirable sca effects for all the traits simultaneously. However, the crosses Arka Kusumakar x Local Long, GBL-1 x Pusa Purple Long, Arka Nidhi x GOB-1, Arka Nidhi x Pusa Kranti and SBPL-27 x GOB-1 were found to be desirable for most of the traits.
