摘　　要：海南岛西部地区桉树无性系选择研究结果表明:19个无性系树高、胸径、蓄积量、冠幅及生根能力差异显著,包含的8个品种材积生长排序:尾×细杂交桉>尾×赤杂交桉>斑皮桉>赤桉>尾叶桉>细叶桉>刚果12号桉>雷林1号桉。综合评价,杂交桉TH9113、TH9117、TH9211、TH9224、赤桉CLY01、斑皮桉9401、尾叶桉U9101 7个无性系生长快,扦插生根能力强,可列为重点发展的桉树优良无性系。19 Eucalyptus clones were selected in north-western region of Hainan Island,the results showed that there were significant differences on tree height,DHB,crown and ability of cut-rooting.The growth falls within 8 Eucalyptus species was followed rank: E.urophylla×E.tereticomis > E.urophylla× E.camaldulensis > E.maculata> E.camaldulensis > E.urophylla > E.tereticomis > E.12ABL > E.leizhou No.1.TH9113、TH9117、TH9211、TH9224、CLYO1、M9401 and U9101were selected as superior clones with a higher potential of productivity for the region to develop large-scale eucalyptus plantation.In the future,it would be to enhance the research of cross breeding in order to get the higher genetic gain.
