Outline of Final Research Achievements

There are some weed species which migrated to other areas from native distribution area and again immigrated to original areas after long migration. It is very difficult to distinguish such weeds morphologically from original native one, because the two strains are the same species. In this experiment, we try to develop the SSR markers which distinguish such two weed strains of major upland weeds, Setaria and Digitaria. We could not develop useful SSR markers to distinguish the two strains of Setaria weeds, but some iPBS markers will be useful for distinguishing the two strains of Digitaria weeds.
