Line x tester analysis of 25 crosses obtained from 5 lines and 5 testers were made for 14 yield and its associated characters in mungbean. Among the parents, PDM 84-178, PS 16, Tap7, Chinamung, CO 4 and KM 1883 which scored high status were found to be best combiner for most of the characters studied. Nine hybrids exhibited highest per se performance and sca effects for most of the characters studied. The hybrid, Tap7 x KM1883 was the top performer for sca effects. The variances due to specific combining ability (SCA) were found be higher than general combining ability (GCA) variances for all the fourteen characters studied indicating predominance of non-additive give action in the inheritance of the characters studied.

Abstract


Line x tester analysis of 25 crosses obtained from 5 lines and 5 testers were made for 14 yield and its associated characters in mungbean. Among the parents, PDM 84-178, PS 16, Tap7, Chinamung, CO 4 and KM 1883 which scored high status were found to be best combiner for most of the characters studied. Nine hybrids exhibited highest per se performance and sca effects for most of the characters studied. The hybrid, Tap7 x KM1883 was the top performer for sca effects. The variances due to specific combining ability (SCA) were found be higher than general combining ability (GCA) variances for all the fourteen characters studied indicating predominance of non-additive give action in the inheritance of the characters studied.
