Gamma Radiation Induced Mutations in Black gram (Vigna mungo (L.) Hepper)

The present investigation was conducted during the kharif season of 2009, seeds of black gram [Vingo mungo (L) Hepper] variety TPU-4 was exposed to gamma rays doses at 10, 20, 30, 40, and 50KR. Wide range of chlorophyll and viable morphological mutations affecting almost all the parts of plant and were isolated in M2 generation. Mutant characters were grouped as Chlorophyll, leaf, and pod mutants. Chlorophyll mutations include albino, coppery leaf, light green leaf, variegated leaf, waxy leaf, xantha leaf. Leaf mutations were lanceolate, narrowrugose leaf, round cuneate leaf, unifoliate, and tetrafoliate leaf. Pod mutations were lobed and hairy pods. Higher chlorophyll mutation rate was observed with gamma rays dose of 30KR.
