摘　　要：对40个思茅松高产脂无性系产脂力测定的结果表明,所有无性系的产脂力均大于对照,较对照产脂力平均提高达210%;无性系间产脂力存在极显著差异,其遗传力为0.83。初步筛选出8个高产脂的优良无性系,入选无性系产脂力的对照遗传增益为281%。The resin - producing capacity of 40 high resin - producing clones of Pinus kesiya var. langbianensis was studied. The result showed that the resin - producing capacity of all clones was higher than CK, and the average resin -producing capacity was 210%. The resin -producing capacity among the clones had a significant deference. The family heritability was 0. 83.8 superior clones with high - resin -yield were selected, and the genetic gain to CK was 281%.
