| 摘 要： | 通过对杂种桉选优结果进行相关比较和方差分析,结果表明:五株优势木法适合于杂种桉的优树选择,所筛选出的优树无性系在胸径、树高和木材产量上都与相应的优树存在着极显著的偏相关,同时,所营造的无性系林其重复力(R)均大于0.97,经与W5无性系作对照,选育出LH1、M1、SH1三个优良桉树无性系,优树选择可靠率达20.0%。

| Abstract: | The selection results from hybrid eucalypt were gotten by correlation and variance analysis,and the results were showed the method of comparison trees with five trees was considered as a suitable method for hybrid eucalypt selection,and the breast diameter,tree height and timber yield of the clones from the selected elite trees had a partial correlation relationship with those of the selected trees,meanwhile the repeatability of their clone plantations were all more than 0.97,and the elite clones of LH1,M1 and SH1 were selected out with the comparison of W5 clone and their reliability rates was over 20.0%. |
