摘　　要：对广西国有东门林场37个杂交桉无性系进行造林对比试验,观测其6年生不同桉树无性系的保存率和生长量。结果表明,6年生桉树无性系间的树高、胸径及材积组间均呈显著性差异,达极显著水平(P<0.001),组内差异不显著。根据6年生的生长量分析,初步筛选出DM9、DM25、DM27、DM28、DM31等5个优良无性系。A comparison trial consisted of 37 hybrid Eucalyptus clones was established in Dongmen Forest Farm to assess the preservation rate and growth performance of the 6-year-old different clones. Results showed that there were significant differences（ P〈0. 001） among different clones in tree height,diameter at breast height and volume,while the differences within the same clones were not significant,indicating an inconsistent genetic performance among different clones. According to the analysis of growth performance,such 5 superior clones as DM9,DM25,DM27,DM28 and DM31 were preliminarily selected.
