Fragrant cyclamen cultivar (${it C. persicum}$ $$times$$ ${it C. purpurascens}$), that bloomed purple flower containing malvidin 3,5-diglucoside as the major anthocyanin, was irradiated with a 320-MeV carbon-ion beam at 0-16 Gy to increase flower color variation by mutation. Some of the M2 plants derived from self-pollination of M1 plants irradiated at 2 Gy were flower-color mutants that retained desirable flower shape, flower size, and leaf color. One of the mutants bloomed novel red-purple flowers, the major anthocyanin of which was delphinidin 3,5-diglucoside. Because the major anthocyanins in flowers of ${it Cyclamen}$ spp. were previously restricted to malvidin, peonidin, and cyanidin types, the generation of a cyclamen containing mostly the delphinidin-type anthocyanin is an important breakthrough in cyclamen breeding. We expect this mutant to become not only a commercial cultivar itself, but also a valuable genetic resource for cyclamen breeding.

One of the fragrant cyclamens, Kaori-no-mai, blooms purple flowers containing malvidin 3,5-diglucoside as the major anthocyanin. Here, we irradiated etiolated petioles of Kaori-no-mai with a 320-MeV carbon-ion beam to increase flower color variation by mutation. Some of the M2 plants derived from self-pollination of M1 plants were flower-color mutan. One of the mutants bloomed novel red-purple flowers, the major anthocyanin of which was delphinidin 3,5-diglucoside. The major anthocyanins in flowers of ${it Cyclamen }$ spp. were previously restricted to malvidin, peonidin, and cyanidin types, therefore, the generation of a cyclamen containing mostly the delphinidin-type anthocyanin is an important breakthrough in cyclamen breeding. We expect this mutant to become not only a commercial cultivar itself, but also a valuable genetic resource for cyclamen breeding.

In this study, using several flower-colored mutants and their parents, we analyzed flavonoid composition in flowers by HPLC, and isolated anthocyanin biosynthetic genes by degenerate PCR. We isolated several anthocyanin biosynthetic genes from C. graecum, C. purpurascens and fragrant cyclamen cultivars. Then, we analyzed their expression patterns between wild-type and flower-colored mutants. Based on their comparison, we selected candidates for anthocyanin biosynthetic genes and confirmed their enzymatic activities in vitro. Furthermore, we also demonstrated the effectiveness of PCR-based screening method in early growth stage of mutagenized cyclamen, using newly developed DNA markers.
