Studies on effect of physical and chemical mutagens on Vigna mungo (L.) Heppe

Mutation breeding is one of the trending methods in the development of desirable mutant. Induced mutagens including both physical and chemicals are commonly used in crop improvement. The present investigation was conducted during the kharif season of 2022; seeds of black gram [Vigna mungo (L) Hepper] were treated with sodium azide 0.01, 0.02, 0.03%, ethyl methane sulphonate 0.05, 0.10, 0.15% and exposed to gamma rays doses at 10, 20, 30, 40, 50 and 60 KR to determine the effects on morphological characters. Wide range of chlorophyll and viable morphological mutations affecting almost all the parts of plant and were isolated in M2 generation.
