摘　　要：通过采用山杨 7个种源 1 1株优树与美洲山杨 8个优树进行杂交 ,共进行 88个组合 ,其中 46个杂交获得成功 ,进行播种育苗 ,建立子代测定林。 5年的试验结果表明 ,山杨作母本时 ,以苇河种源较好 ;美洲山杨作父本时T 32 5 7和T 2 8 5 6较好 ,其它亲本的杂交组合尚需进一步观察。而在部分山杨与美洲山杨杂交种无性系试验林中 ,Id42 3、Gd42 1、Ca42 1和Bd44 1生长速度快、光合能力较强 ,抗病虫能力强 。In this paper 11 plus trees from 7 provenances of Populus davidiana were crossed with 8 plus trees of from P. tremuloidesill Minisuda USA in 1995. 46 crossing combination among 88 combination were done successfully and obtained seed. It indicates from 5 years test plantation that Populus davidiana from Weihe Heilongjiang of China is better as female parent, and T-32-57 and T-28-56 of P. tremuloides from Minisuda of USA as male parent. Id32-3, Gd42-1, Ca42-1 and Bd44-1 is superior clone.
