The in vitro bulbs of Narcissus tazetta var. chinensis were treated with different concentrations of colchicine and different doses of 60Co gamma -ray in order to seek the appropriate artificial mutagenesis condition. The results showed that it was appropriate to treat the bulbs with 50-100 mg colchicine/litre for 12 days and that the optimum radiation dose was 30 Gy.
