摘　　要：以40个3年生的高产脂思茅松嫁接无性系的树高、胸径、抗松梢螟能力、针叶叶绿素含量及产脂力5个指标为分类指标,采用系统聚类的可变类平均法进行无性系的聚类分析.根据聚类结果把无性系分成3类,初步评选出生长最好、抗松梢螟能力较强、产脂力最高的6个优良嫁接无性系.Based on some collected data of tree height, DBH, pest resistance, chlorophyll content and resin capacity of 40 high-resin yield grafting clones of Pinus kesiya var langbianensis, the flexible-beta method was used for a cluster analysis. And according to the result of this cluster analysis, the clones were divided into 3 groups and 6 superior grafting clones with the best growth performance, high anti-Dioryctria splendidella Herrich-Schaffer ability and the highest resin yield were preliminarily selected.
