Zusammenfassung:The invention discloses a Co-gamma ray radiation mutation breeding method for bougainvillea speetabilis with golden-yellow leaf edges. According to the method, bougainvillea speetabilis seedlingsare subjected to radiation treatment by utilizing Co-gamma rays with the dosage of 44-46 Gy, the dosage rate is 1.0-1.1 Gy/min, the radiation treatment time is 40-45 min, and a target mutant capable of stably inheriting the golden-yellow leaf edge character can be obtained after maintenance primary selection and propagation secondary selection. According to the scheme, the mutation rate of thebougainvillea speetabilis is increased, the breeding period of a new variety of the bougainvillea speetabilis is shortened, the defects of long breeding period, low breeding efficiency and small variation of cross breeding and natural bud mutation of the bougainvillea speetabilis are overcome, and the method is simple, easy to implement and high in operability and has important significance in breeding of the new variety of the b
