Abstract: Based on the comprehensive indexes including yield of oil，the economic characters of fruit and its fatty acids composition，25 clones’ quality of Camellia oleifera （oil camellia） Group Gan was evaluated，which provided scientific grounds for breeding and selection of superior oil camellia clones. By the principal component analysis，the article compared the quality of the twenty-five clones and ranked their advantages and disadvantages. The results indicated that the differences among the twenty-five clones were significant，which reached medium intensity variation. Of the eleven indexes evaluating the quality of oil camellia，the oil contents in the fresh fruits，the dry seed producing rate，linoleic acid，oleic acid and the oil production played decisive roles. The ranking of the quality of 25 clones from the best to the worst was as follows：Ganshi 84-8，Ganwu 1，Ganwu 11， Ganshi 83-4，Gangfu 20，Ganwu 16，Gan 71，Ganshi 83-1，Gan 6，Ganwu 24，Ganshi 84-3，Gan 8，Ganxing 48，Gan 55，Ganyong 6，Ganxin 46，Gan 68，Ganwu 15，Gan 70，Ganwu 12，Ganwu 2，Gan 77024，Gan 190，Gan 447 and Ganyong 5. ［Ch，5 tab. 13 ref.］
