95 accessions of wild adzuki bean germplasm resources from China,Japan,Korea and Burma,were analyzed for their morphological genetic diversity.The results showed that wild and weedy adzuki bean were obviously different in some characters,such as plant height,maturity period,seed color and 100 seed-weight and so on.Based on the morphological data,95 accessions were clustered into 5 groups.Wild adzuki bean from Burma and China,were clustered into two groups,respectively.The last three groups were from Japan and Korea.The accessions from Burma,had longest growth period,widest diameter of stem,more plant branch and smallest 100-seed weight.The wild germplasm resources from Guizhou of China had longer plant height,thinner stem,more seeds per pod,longer growth period.The Japanese wild germplasm had highest grain yield per plant.The germplasm with shortest growth period,highest 100-seed weight,highest value in L*,a*,b* were all weedy type from Japan and Korea.
