Summary:The dormant rhizomes of canna (Canna L.) were irradiated with 60 Co gamma-rays and fast neutrons, and of mutagenic effects have been studied during 1983-1985. The results showed that the radiation effects of VM1 generation in the treatment of gamma-rays for "Crimson Canna" (Canna generalis Bailey seemed significant and the mutation frequency of flower colour variation was rather high, ranging from 3.45% to 6%. The optimal dose ranged from 9.2 to 36.8 Gy. The sensitivities among various genetic types were very different. The mutagenic effects of the two kind mutagens have also been compared in this experiment. It was found that gamma-rays were better than fast neutrons, the mutation frequency was low in the continuous retreatment for several generations. Nine flower colour mutants have been selected in the gamma-rays treatment of "Crimson Canna". Among which 3 mutant lines with special flower colour have been selected and are being propagated for commercial uses.
