Combining Ability in Mungbean (Vigna radiata (L.) Wilczek) II. Traits Related to Indetemination

Combining ability study was carried out on the components of synchronization in maturity and determinate growth habit in mungbean, using 6$\times$6 diallel cross. Both additive and non-additive gene effects were found conditioning the inheritance of days to first flower, days between first pod and 90% pod maturity (DDd1), plant height from first pod stage to 90% pod maturity (DDhl, DDh2, and DDh3). Only non-additive gene action was important in degree of determination from first pod stage to 90% pod maturity (DDd2). While only additive action was important in plant height at first flower. The predominant additive gene action was observed in all traits but non-additive was significant in only DDd$_2$. For synchronization in maturity, determinate growth habit, and their components, the best combiners were NM92, VCl560D, and NM89, whereas the best indeterminate combinations were NM92 $\times$ NM89, NM92 $\times$ VCl560D, and NM92 $\times$ ML-5.
