鲁山杨等杨树无性系对比试验初报

Primary Report on Result from Contrast Test for Poplar Clones Including Lushan Poplar

以从辽宁等地引进及湖北省内选育的共20个杨树无性系为材料,于2000年3月在中国杨树委员会良种繁育基地(武汉市黄陂区武湖乡,下同)进行造林试验,根据试验期间调查的结果,对其生长差异性分析及遗传力的估算表明:参试杨树无性系的树高、胸径和材积生长有极显著差异,特别是鲁山杨(辽宁杨),圣山杨(盖杨)、欧美46及欧美14等几个无性系显示出良好的生长趋向,极显著优于对照品种中嘉8号和中潜3号。试验结果有助于我们在营建杨树丰产林时,选择这些优良的杨树无性系,从而得到较大的经济效益和生态效益。

An afforestation test was carried out during March of 2000 over breeding base of improved variety constructed by Chinese Poplar Committee (i. e. Wuhu Countryside in Huangpi District of Wuhan City and the same below) by use of 20 poplar clones introduced from Liaoning province and etc. and selectively bred within Hubei province as material. Based on results from investigation during period of test,it was indicated through analysis on growth difference and estimation to genetic force that there are significant difference among tested poplar clones in tree height and breast diameter and volume increment, especially the fact that there is a tendency to show good growth among several clones such as Lushan poplar (Liaoning poplar), Shengshan poplar (Gai poplar), Canada poplar 46 and Canada poplar 14 and etc., which is very significantly superior to contrast varieties such as Zhongjia No. 8 and Zhongqian No. 3. The test results are beneficial to our selecting these excellent poplar clones and thus greatly raising economic and ecological benefits when constructing high yield and fast—growing forest for us.
