Outline of Final Research Achievements

In order to verify the value as ethnobotanical cultural assets of primrose, azalea, and Japanese iris of classic garden plants raised from the Japanese wild relatives at the Edo period, the analysis which combined the genome information on the diversity of flower traits, and the history and the cultural background of horticulture was tried.
In primrose, the changes to horticulture cultivars from wild primrose were made clear from the analysis of quantitative variation of petal form and the DNA polymorphism. It showed clearly that various floral traits were taken in from the Japanese wild iris, and petal form variation was able to be clarified on the gene level in the azalea. In primrose, Japanese wild iris or azalea, we tried to conserve wild populations or local cultivars. These results offer basic information to future national collection creation.
