Outline of Final Research Achievements

The Ginkgo biloba naturally distributes in China. It is considered that the Ginkgo introduced to Japan in thirteenth century. The purpose of the study is to make clear the early stage of artificial propagation route from China to Japan, and distribution expansion in Japan. We investigated Gingko giant trees of more than eight meters of trunk girth in Japan, and genetically analyzed using a microsatellites marker. We also investigate and sampled in China and Korean, and the genetic analysis result was compared. A Gingko in China, Korea and Japan were divided into eight groups (A-H group) as a result of the analysis. Four groups are distributed in China, Korea, and Japan (A, C, D, F), and two groups are distributed in China and Japan (E, G). And,two groups are distributed only in Japan (B, H).
