ABSTRACT
Heterosis and combining ability for 12 characters including pod yield per plant in Indian bean were studied in diallel crosses involving eight diverse genotype, excluding reciprocals. The hybrid JIB (P) 4 x Danitiwala Local found highly heterotic foe pod yield per plant (105.16%), plant height (25.82%) and for pod girth (28.25%). The components of variances due to gca and sca revealed the predominance of additive gene action for all the characters under study. The entry JIB (P) 4 was found to be good general combiner for pod yield per plant and number of pods per plant. The crosses JIB (P) 4 x Dantiwada Local and JIB (V) 7 x JIB (V) 15 were identified as the best combinations which could be exploited for improving pod yield in Indian bean.
