Research Abstract

Using microsatellite analyses we revealed that the extensive introgression between Pyrus ussuriensis, which is a threatened plant distributed in the Kitakami Mountains and P. pyrifolia, which is a prehistorically introduced plant. The introgressed plants are distributed widely in this Mountains, even in natural habitats, whereas the plants estimated as genetically true native grow very limitedly. However, we were able to infer the genotypes of true native plants, their original distribution area and habitats. They will become useful for their future conservation.
