| Outline of Final Research Achievements |
Cytological and phylogeographical studies were performed for Patrinia villosa (Thunb.) Juss. (Valerianaceae), which showed conspicuous infraspecific polyploidy. After analyzing with samples collected in Japan and Korea, we confirmed a series of polyploids from diploid (2n=22) to dodecaploid (2n=132). We also recognized three genetical groups, 1) a group distributed in western Kyushu District and Korea, with 2n=22, 2) a group distributed from Hokkaido and Shiga Prefecture, with 2n=44, and 3) a group distributed westwards from Kinki District to Kyushu District, with 2n=66～132. Patrinia x hybrida Makino, which had been believed to be a hybrid origin between P. villosa and P. scabiosaefolia Fisch. ex Trev., was not an interspecific hybrid, but a result of infraspecific hybridization between cytological races in different ploidal levels.
