摘　　要：对40个思茅松(Pinus kesiya var.langbianensis)高产脂无性系的松香产量进行了测定分析。结果表明:所有无性系的松香产量均大于对照,较对照松香产量平均提高192.4%;无性系间松香产量存在极显著差异。无性系松香产量的遗传力为0.68。初步选择出20个高产脂的优良无性系。入选无性系松香产量的对照遗传增益为178.8%。Measurement results of rosin yield of 40 high resin yield clones showed that the rosin yield of each clone was higher than that of the control, and the average rosin yield increased by 192.4% compared with the control. A significant deference in rosin yield was found between different ＆ones. The family heritability was 0.68. Twenty superior clones with high content of resin were screened out, and the genetic gain was 178.8%.
