柳树属于杨柳科（Salicaceae），柳属（Salix）。柳树的种内种间遗传变异显著。本文通过对两个种间杂种P101和P109的生长性状树高和地径的调查研究表明：两杂种种内差异显著。通过对比和分析，从杂种101群体中选出优良无性系3个，分别是101-70、101-301、101-315；从杂种109群体中选出优良单株3株，分别是109-95、109-107和109-151。
此外，本实验为基础性研究工作，可为以后柳树杂交育种和优良无性系的选育提供依据。

Section of willow trees (Salicaceae), Liu is (Salix). The types of trees planted between genetic variations marked. The adoption of a hybrid of the two types of growth P101 and P109 index tree height and to track research findings indicate : two notable differences within the various complex. Through comparison and analysis from hybrid 101 fine asexual groups of three elected were 101-70, 101-301, 109 groups 101-315; hybrid elected from the fine selection three trees were 109-95, 109-107 and 109-151.
In addition, the experimental work for basic research, for subsequent trees crossbreed fine asexual and provide the basis of the selection.
