Abstract

Plants of the Chrysanthemum variety ‘New Princess’ were irradiated with X- and gamma rays at dose rates varying between 500–2000r X-rays and 1–4 Krad gamma rays. Flower colour changes were induced by both types of radiation and these were accompanied by change in chromosome number and by chromosome fragmentation. Optimum doses were 1000r X-rays and 1 Krad gamma rays. Most of the changes resulted from loss of pigmentation but a number with deeper colours were found. The frequency of mutation was directly proportional to the dose. Other phenotypic changes were also observed. The mutants arise by the formation of chromosomal chimaeras or by the re-arrangement of pre-existing chimaeras.
