Abstract An experiment was conducted to induce novelty using gamma irradiation in annual chrysanthemum (Chrysanthemum coronarium) cv. Local White at IARI, New Delhi, during 2007. The seedlings were irradiated at 0, 2.50, 5.00, 7.50, 10.00 and 15.00 Gray gamma rays. The favourable effect of radiation was perceptible at lower doses (5.00 Gy). Beyond the dose of 7.50 Gy gamma radiation the seedlings did not survive. From the mutated population, 14 types of novel promising mutants comprising semi-double, double and miniature forms were isolated. The flower form varied from marigold, carnation, ranunculus, chrysanthemum, gerbera and dahlia flower types in those seedlings that were exposed to 5.00 Gy gamma radiation.
