Abstract
Black gram (Vigna mungo) (L.) Hepper) is a crucial crop in our country. It belongs to the family Leguminosae and subfamily papilionaceae. Mutation breeding is the tool in the hand of breeder to discover variability in crop population and to make option in the population with the view to bring about more improvement in crop. Genetic improvement through mutation breeding has extention in Agriculture sector to establish new varieties. The two mutagens are employed, chemical mutagens namely Diethyl Sulphate (DES) and sodium Azide (SA) (10 mM to 50 mM) were used at different concentration to induce mutagenesis. The LD50 value and germination percentage was noted to each treatment. According to results the LD50 was observed in 40 mM of DES and 30 mM of SA.
