Combining ability and inheritance of pod and cluster number inPhaseolus mungo L.

A set of sixPhaseolus mungo lines was studied in a diallel cross over two generations to investigate general and specific combining ability and mode of inheritance for cluster and pod number. General combining ability effects were more important for both characters.Per se performance appeared to be a good index to rank the parental lines for general combining ability. Additive gene effects with partial dominance to overdominance for these traits were noted. High cluster and pod number seem to be governed by recessive genes.
