Abstract
Five evergreen azalea species (Rhododendron macrosepalum, R. mucronatum var. ripense, R. scabrum, R. indicum, and R. eriocarpum) and 3 groups of cultivars (Ryukyu, Mochi, and Ookirishima azaleas) were examined for aspartate aminotransferase isozyme bands, "112" and "104", which were detected in Kurume azalea cultivars but not in their known original species, R. kiusianum, R. kiusianum var. sataense, and R. kaempferi. "112" band is peculiar to R. mucronatum var. ripense, whereas "104" band is limited to R. macrosepalum and R. scabrum among the species related to the breeding of the principal domestic evergreen azalea groups. In addition, Ryukyu, Mochi, and Ookirishima azaleas, whose original species are R. macrosepalum, R. mucronatum var. ripense, and R. scabrum, possess either "112" or "104" band. Therefore, "112" and "104" bands detected in Kurume azalea cultivars may be duly derived from these three species.
