Abstract: Variability in forty genotypes for twelve characters were studied in winged bean. The number of pods per plot showed maximum GCV and PCV among the traits followed by seed yield per plot, number of pods per plant and seed yield per plant suggested presence of more variability. The least GCV were recorded for days to first pod maturity followed by days to 50% flowering. In the present study all characters showed high heritability except pod length and pod width. Characters like number of pods per plot, seed yield per plant, 100 seed weight, seed yield per plot, number of pods per plant and number of seeds per pod having high heritability estimates associated with high genetic advance as per cent of mean suggesting additive genetic control. Thus, these characters could be improved through simple selection. The expected genetic advance expressed as percentage over mean exhibited high magnitude for traits no. of pods per plot (61.06), seed yield per plot (53.29), no. of pods per plant (52.30). On the contrary low estimates were found for pod width (1.86), days to 50% flowering (11.72), days to first pod maturity (11.72).High heritability coupled with high genetic advance as percent of mean was observed for no. of pods per plot and 100 seed weight suggesting the role of additive gene action in these traits. Thus, these characters could be improved through simple selection.
