摘　　要：连续5a对闽北浦城引种的11个油茶优良无性系的生长及果实经济性状进行跟踪调查测定。结果表明:不同油茶无性系的树高、地径、冠幅面积、果实性状及产量均存在显著或极显著差异;11个无性系的年均冠幅产果在1.01~2.74 kg·m^(-2)之间,年均产油268.92~1011.75 kg·hm^(-2),其中闽48、闽60、长林3号、长林40号、闽43的产量较高,年均产油超过油茶优良无性系年均产油标准值450 kg·hm^(-2)的79.55%~124.83%,适宜在浦城县推广种植;赣447、赣石84-3无性系的产量较低,不适宜在本地推广种植。The growth performance, fruit yield and fruit economic traits of 11 Camellia oleifera superior clones introduced in Pucheng, a county located in Northern Fujian were investigated for 5 consecutive years. The results showed that there were significant differences in tree height,ground diameter, crown area, fruit traits and oil yield among different clones. The average annual fruit yield in unit crown area of 11 clones was between 1.01 kg·m^(-2)and 2.74 kg·m^(-2), and the average annual oil yield was between 268.92 kg·hm^(-2)and 1011.75 kg·hm^(-2). Among them, Min48, Min 60, Changlin 3, Changlin 40 and Min 43 had higher yield, of which the average annual oil yield was 79.55% ~ 124.83% higher than the standard value(450 kg·hm^(-2)) of C. oleifera superior clones, so they were suitable for planting in Pucheng County. Nevertheless, the yield of Gan 447 and Ganshi 84-3 were relatively low, so they were not suitable for planting in local.
