Genetic distances estimation and clustering analysis were made on the base of 19 characteristics of 15 rice cultivars and 17 wild rice varieties.The results Showed that rice cultivars and wild rice varieties were two categories.Common wild rice varieties from same regional distribution were not necessarily closely related in consanguinity.Seven ecodemes were clustered according to the values of genetic distances which are important genetic parameters and can measure the consanguinity among ecodemes.The results mentioned above provided the theoretical basis for utilization of germ plasm resource and can be used in se-lecting parents for hybridization breeding.
