Mutation breeding is one of the most important breeding methods for ornamental plants. Chrysanthemum "Bacardi" is the genus that has the richest mutant varieties in ornamental plants.
The objective of this study is to create variation by gamma irradiation and improve traits by mutation breeding. For this aim, in vitro bud explants of the white Bacardi variety were irradiated by gamma radiation at 20 Gy. In vitro subcultures were continued until the M1V4 period, and observations were obtained during this period.

Some changes were observed in the heights and flowers of the plants, such as:
- variable flowers, flowering time
- differentiation on plant length
- flower number per bunch
- ray floret differentiations.
The changes of the ray florets were determined as color changes to pink and yellow. Mutation frequency was calculated by 1.1% of the population. Approximately 0.9% of useful mutant lines were determined from the selected mutants.
