In order to obtain horticulturally useful mutants of spp., tissue-cultured shoots were irradiated with ion beams at TIARA. The shoots were irradiated with carbon ions in the range of doses from 1 to 5 Gy. Irradiated shoots were transplanted to culture vessel for rooting. 247 plants were acclimated and then settle planted in the field. After blooming, we investigated mutants by focusing mainly on flower shape and color. As a result, several flower shape and flower color mutants are obtained even from 1-Gy irradiated shoots. We are planning to obtain more mutants by increasing study population. Thereafter, we will propagate horticulturally useful mutants and investigate the stability of their characteristics.
