Studies of the last two decades demonstrated that the ion beams generated by accelerators are useful for plant mutagenesis. The ion beams are now widely used to expand genetic resources in many plant species. Alternation of flower colors is the most frequently applied target and the several studies showed that the ion beams induce the wider mutation spectrum than -rays. However, mutability differs among the strains, i.e., the range of mutant traits are generally limited by the starting materials. In this study, we aimed to accumulate the knowledge regarding the relationship among flower color, pigment molecules and the genes for enzymes involved in pigment biosynthesis in cyclamen and carnation, in order to help in understanding the genetic background and choosing suitable starting materials.
