Dry and healthy seeds of Ocimum sanctum L. were irradiated with 200, 400, 600 Gy gamma rays. Seeds were also treated with sodium azide (SA) (0.001%, 0.002%, 0.003%) and ethyl methanesulphonate (EMS) (0.1%, 0.2%, 0.4%). All the three mutagens were found to induce chlorophyll mutations. They were albino, xantha, chlorina and viridis. The chlorophyll mutants survived for about 30–35 days and then died. The SA was found to produce maximum chlorophyll mutations followed by gamma rays and EMS.
