Abstract: Based on the studies on cultivar resources of sweet osmanthus in Hefei of Anhui Province, 39 cultivars are classified into four groups,among them, 21 in Luteus Group,8 in Albus Group,6 in Aurantiacus Group, 4 in Siji Group. Each group is formulated a cultivar classification system ,and characters of each cultivar are described. We found some problems existed in resource.The first , cultivars of sweet osmanthus flowering in autum are more than the cultivars of sweet osmanthus flowering in four seases.The second,the producers do not have clear targets of produce.The third , the producers are lack of classification knowledges about sweet osmanthus.The last, there is not a garden which only cultivate sweet osmanthus. In view of these problems, the researchers should introduce more varieties of Siji sweet osmanthus from the other areas.To teach the producers some knowledges about classification of sweet osmanthus.To guide and help the producers construct the garden just for cultivating sweet osmanthus.
