摘　　要：对湖北省竹山县复选出的28株油茶优良单株的果实性状进行了分析,主要从鲜出籽率、干出籽率、种仁含油率和鲜果含油率四个关键经济性状决选出A10、A14和A27三株优树,其中A27单株的四项经济性状分别达到了48.42%、30.05%、52.74%和11.34%。对28株油茶果实性状进行了分析,结果表明,出籽率和含油率等内在性状是优树选择的关键,这为油茶选优工作提供了重要的技术支持。Fruit traits of 28 superior Camellia oleifera selected from Zhushan County were analyzed.Based on four key economic traits(the weight rate of fresh seed in fresh fruit,the weight rate of dry seed in fresh fruit,oil content of kernel and the oil content of fresh fruit),A10,A14 and AA27 were selected as final optimal trees.The value of the four economic traits mentioned above in A27 were 48.42%,30.05%,52.74%and 11.34%.Major traits of fruits from the 28 trees were also analyzed.The results indicated that the inner traits,related to seed content and oil content,were the key of selection rather than fruit size and appearance.Those results provided essential supports for superior tree selection of Camellia oleifera.
