摘　　要：通过对9个广西油茶优良无性系的果实经济性状指标进行分析,结果表明:各无性系间指标性状变异明显,果实经济性状间关系密切,9个性状指标被转化为2个主成分,累积贡献率达到了78.174%,果皮厚、仁含油率、鲜出籽率占决定地位,贡献率为52.448%;各参试无性系的果实经济性状优劣依次为:岑软1号、岑软11号、岑软3号、岑软23号、岑软2号、岑软22号、桂无1号、桂无4号、岑软24号。Through analyzing the economic characters of fruits from 9 clones of Camellia oleifera of Guangxi, the results indicated that the differences among the clones were significant and the relation between the economic characters was dose. According to the cumulative variance contribution which reached 78.174 %, two principal components which reflected the main economic characters of fruit were determined. For the variance contribution reached 52. 448 %, the thickness of peel, the oil con- tents in the pip and the fresh seed producing rate played decisive roles. The ranking of the economic characters of 9 clones from the best to the worst was as follows： Cenruan 1, Cenruan 11, Cenruan 3, Genruan 23. Cenruan 2, Genruan 22, Guiwu 1, Guiwu 4, C.enruan 24.
