Abstract: Combining ability analysis was conducted for
grain yield and yield Components viz., plant height. branches per plant,
pods per plant, pod length, seeds per pod, 100 grain weight in a five
parent diallel population of mash (Vigna mungo) including parents, F1's
and reciprocals. Non-additive gene action (dominance or epistasis)
contributed the major portion in total genetic variance for all the
plant characters studied.Significant reciprocal effects were also
observed for all the characters which indicated the importance of
maternal contribution iii the performance of hybrids. Therefore a
biparental mating among the selected F2 segregants followed by selection
in advanced generations, F6 or later, is suggested. The genotype 87/88
proved to be the best general combiner for pods per plant and grain
yield and could be exploited in future mash breeding programme to
develop high yielding varieties.
