Abstract:: Chinese yam is the main source of income in some rural areas of Hainan，which made the importance contribution to develop efficient agriculture and promote the farmer’s income.Since the introduction of chaos，there exists the same species with different names or the same name with different species，which is inconvenience to the production introduction and genetic improvement.In order to identify preliminarily the diversity of germplasm resources of cultivated Chinses yam in Hainan province，twenty-four Chinese yam germplasm resources were collected from Hainan province of China，field plant were conducted and botanical characteristics were observed and measured at the same time，clustering analysis method was applied to conduct a preliminary analysis for the classification and diversity.The results showed that these germplasm resources were classified into two species(Dioscorea batatas Decne.and Dioscorea alata L.)and three groups by clustering analysis (including Dioscorea batatas Decne.，long column variety and flat block variety).This study would provide the materials’ information for introduction，genetic improvement，identification，production and processing in future.
