| Outline of Final Research Achievements |
In order to elucidate the process of development of Japanese azalea cultivars from wild species and they spread abroad, flower form, flower color, habitat soil and mycorrhizal fungi of wild species and cultivars were investigated. The responsible MADS-box gene information of flower form mutations; hose-in-hose, double, spider type and long-lasting flower were obtained. The spread of the mutational flower form gene and the plastid of a Japanese wild species were verified in foreign azalea cultivars. As interspecific hybridization progressed, anthocyanins and coloration factors become more complicated, and the diversity of flower color was increased. Ericoid mycorrhizal fungi were colonized in the hair roots of wild azaleas in an oligotrophic soil environment, and the microbial floras were varied in the wild habitats and cultivation areas. These results provide the basic information of the future azalea breeding.
