通过在优树无性系的基础上进行优良无性系选育和半同胞子代测定 ,选育出XLC6等 6个油茶优良无性系 ,其产油量为 4 90 98～ 990 86kg/hm2 ,比参试无性系平均值增产 35 4 %～ 16 8 0 % ;还选育出XLJ2和XLJ14两个优良家系 ,其产油量分别为 5 12 2 0kg/hm2 和 4 90 98kg/hm2 ,分别比对照增产 38 5 %和 32 8%。同时结合国家和地方造成林项目的需要 ,逐步示范和辐射推广 1 33万hm2 ,取得了很好的经济和社会效益。
Six elite clones of Camellia oleifera such as XLC6 were bred by clonal selection and semi-sibling generation on the basis of elite clones, and their oil yield was 4 90 98 ~ 9 90 86 kg / hm 2, The mean value of clones increased 35.4% ~ 16 80%. Two elite families, XLJ2 and XLJ14, were also bred with oil yield of 5 12 20 kg / hm2 and 4 90 98 kg / hm2, respectively, 38 5% and 32 8%. At the same time, with the needs of the forest project caused by the country and the locality, we have gradually demonstrated and promoted 11,300 hm2 of radiation and achieved good economic and social benefits.
