Outline of Final Research Achievements

Exact identification and classification of important traditional cultivars of Japanese flowering cherries maintained at major official flowering cherry collections over Japan was conducted based on morphological and genetic analyses. Exact cultivar names were given to the individuals which were the same clones as the cultivars in the three cherry collections investigated by the author's former study, and conversely the importance of conservation as unique resource was pointed out on the individuals which were unknown new clones or cultivars. The wild species concerned with the origin of each cultivar were estimated by the comparison of genetic variation between cultivars and wild cherry species. Many cultivars were clarified to be derived from hybrids among several wild species. These findings should be useful information for maintenance and utilization of genetic resources of Japanese flowering cherries with many traditional cultivars.
