Mutagenic Effect of Ethyl Methane Sulfonate and Sodium Azide on Pod Characters in Winged Bean[Psophocarpus tetragonolobus (L.)DC.]

Abstract :

In the present studies an attempt was made to estimate the induced variability with reference to quantitative parameters in M2 and M3 generations. A through statistical analysis of the data on individual quantitative characters was done to analyses the effect of mutations in shifting the mean and variance in either direction. The effect of chemical mutagen on pod characters, the productivity in terms pods per plant as compared with control/ normal plants was found to be better in some of the viable mutants like high yielding, anthostem mutant, long pod mutant and flat pod mutant in both the varieties of winged bean such as II–EC–178313 and 2I–EC–38825. The other mutants like early flowering, late flowering and early maturing were observed in both the varieties of winged bean with slightly reduced pods per plant as compared with control.
