Research Abstract

In the present study, mechanism of the turning of flower color and the coloration of marginal picotee petals in cyclamen cultivars were clarified. Interspecific hybrids between cyclamen cultivars with petals turning their color or with marginal picotee petals, and wild Cyclamen species with useful characteristics were obtained by the ovule culture. The amphidiploids were also obtained by the ovule culture with colchicine treatment. Some plants of the interspecific hybrids had petals turning their color or those with marginal picotee. These results indicate that the breeding of new cyclamen by using cyclamen cultivars with petals turning their color or with marginal picotee petals, and wild Cyclamen species
