Study on Irradiative Mutation Breeding of Canna generalis Bailey
摘要
Abstract
[ Objective] The reference for the new Canna generalis B. variety breeding was provided through the research on its mutation principle in treatment of60 Co-γ ray. [ Method ] Canna generalis B. seed and rhizome were irradiated by 60Co-γ ray with five irradiative dosages and the mutation efficiency was analyzed. [ Result ] The rate of seed germination, the rate of seedling growth and the rate of rhizome survival of Canna generalis B. was decreased and the mutation rate was raised with the increment of irradiative dosage. When the irradiative dosage was over 60 Gy, the mutation rate did not vary and the plant was heavily damaged without ornamental value. There were low frequency of mutation and little variation of color and pattern of flower in the irradiation of 60Co-γ ray to rhizome, and only was some mutations in its flowering perioddelaying and plant height shown, which was not with the genetic character. [ Conclusion ] The suitable radiation dosage for Cannna generalis B.seed was 40-60 Gy and for rhizome, 10-20 Gy.关键词
