摘　　要：通过高产脂马尾松初级种子园产脂力测定 ,结果表明 :14个 3重复和 19个 2重复无性系间的差异都达到极显著性水平。无性系平均重复力为 79 3%～ 86 4 % ,遗传增益为 6 6 9%～ 86 1%。对 6 1个无性系 10 8个幼年期单株产脂力调查 ,发现有 14个单株产脂力特别高 ,其中有 3个单株 10cm割沟单刀产脂量超过 2 0g ,有 8个单株 10cm割沟单刀产脂量超过 10 g。The results showed that the differences among 14 3-replication clones and 19 2-replication ones all reached the extremely significant level.The average clonal repeatability was 79.3%～86.4%,the genetic gain was 66.9%～86.1%.The investigation of resin-producing capacities of 108 single trees belonged to 61 clones in the juvenile period showed that single-tree resin-producing capacities of 14 clones were extremely high,the resin-producing yields of 10 cm long cupping tapping faces of 3 clonal single trees were over 20g among them,those of 8 single trees were over 10g.
