Physical and chemical mutagen induced foliar variations in Ocimum sanctum Linn.

Foliar variations in OCimum sanctum Linn. were induced by physical (gamma rays) and chemical mutagens: SA (Sodium azide) and EMS (Ethyl methanesulphonate). The seeds were irradiated with 200, 400, 600 Gy gamma rays. Seeds were also treated with SA (0.001%, 0.002%, 0.003%) and EMS (0.1%, 0.2%, 0.4%). Different types of foliar variations were recorded from seedling to maturity stage. They were in the form of broad, large, small or abnormal leaves (irregular lamina, notch at leaf apex, changed leaf shape, leaf margin and fused leaves).
