| 摘 要： | 对 13个尾叶桉×细叶桉杂种、10个尾叶桉×赤桉杂种、1个尾叶桉× (尾叶桉×细叶桉 )杂种、1个尾叶桉种内控制授粉子代、5个尾叶桉母本的自由授粉子代和 1个尾叶桉×细叶桉F1自由授粉子代的比较研究表明 ,家系间树高、胸径和材积的差异均达 0 0 1显著水平。选择出优良杂种和子代 14个以及优良单株 12株。优良单株可以作为无性系比较试验的材料 ,优良杂种的优良单株可以用于建立下一世代的育种群体。这为优良杂种单株的无性系化和进一步的桉树杂交育种提供了有效的遗传材料。

| Abstract: | Progeny test was made with 13 hybrids of Eucalyptus urophylla × E.tereticornis, 10 hybrids of E. urophylla × E.camaldulensis, 1 hybrid of E. urophylla × (E. urophylla × E.tereticornis), 5 open pollinated families from the maternal trees of E. urophylla, and 1 open pollinated family from E. urophylla × E. tereticornis. Differences in height, diameter and volume were found at 0.01 significance level both among families and among replicates. Significant replicate among difference might be due to the uneven site condition to which hybrid was susceptible. Fifteen superior families and twelve superior hybrid individuals were selected out for further hybridization and clone test purposes. |
