Abstract

To conserve biodiversity in an eco-system, it is important to clarify a genetic structure of native species for preventing genetic disturbance in case of revegetation. In this study, the genetic structure of Imperata cylindrica in Kinki district is clarified using 120 clones by AFLP analysis. Genetic differentiation was scarcely found among local populations of the species, but a latitudinal cline seems to be found in the district. It is adequate to prevent from transplanting of clones originated at a distance of more than ca 100 km to avoid genetic disturbance of the species in the district.
