Abstract: Seeds of two mungbean varieties viz., WGG-42 and LGG-460 were treated with various dose/concentrations of gamma radiation (200, 300, 400, 500 and 600 Gy) and ethyl methane sulphonate (0.2%, 0.3%, 0.4%, 0.5% and 0.6%) and sodium azide (1 mM, 2 mM and 3 mM) for studying the effect of the mutagens on seedling emergence (%), seedling survival (%), seedling height (cm), pollen fertility (%) and seed fertility (%) in M1 generation. The increasing dose/concentration of mutagens, decreased seedling emergence (%), seedling survival (%), seedling height (cm) and pollen fertility (%) in both the varieties of mungbean. The reductions in all these traits were observed to be more prominent in SA treatments followed by EMS and gamma rays treatments. The variety WGG-42 was found highly sensitive to various mutagens when compared with LGG-460.
