TRACT
The purpose of this study was to study the effect of
gamma irradiation and in vitro culture on mutation
induction of flower color in Catharanthus roseus. A
number of plants were regenerated from irradiated
internode explant. Tow cultivars from previous study
Rosea and Alba, and four doses of gamma irradiation (0.0,
0.5, 0.75 and 1.0 Gy) were applied. Obtained results
indicated that both 0.75 and 1.0 Gy irradiation doses were
the most effective in inducing mutation in flower shape
and color, while the dose of 0.5 Gy was effective in
inducing mutation in leaf form.
