摘要: 通过采用山杨7个种源11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-32-57和T-28-56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,是有希望的杂交种。

Abstract: 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.

Key words: Populus davidiana, P. tremuloides, crossing breeding
