Phenotypic and molecular effects of chronic gamma irradiation on Curcuma alismatifolia

Mutation breeding is one of the methods for generating genetic variation and obtaining new cultivars of ornamental plants during the past decades. In present study, the effects of four doses (0, 14.6, 33, and 87.4 Gy) of chronic gamma irradiation on three cultivars of Curcuma alismatifolia and one C...

In present study, the effects of four doses (0, 14.6, 33, and 87.4 Gy) of chronic gamma irradiation on three cultivars of Curcuma alismatifolia and one Curcuma hybrid were investigated.
