摘　　要：该文对８个白杨派基因型和５个黑杨派基因型组成的２１个杂交组合进行了黑白杨派间杂交试验研究．结果表明：①单交组合没有得到苗木，２０％的三交组合和６７％的双交组合得到了苗木；②三交组合所得苗木形态为偏母本型，双交组合苗木形态经１５个形态性状的系统聚类分析，有的可分为３类：偏母本型、中间型、偏父本型，有的为明显的偏父本型；③三交组合所得苗木生长量小，有的为侏儒状，同一双交组合所得苗木生长差异很大。Twenty one intersectional crosses of Populus between 8 genotypes of Leuce and 5 genotypes of Aigeiros have been studied in this paper. The results show that,① hybrids could be obtained from 20% of the triple crosses and 67% of the double crosses but none from single crosses; ② the morphology of the hybrids derived from triple crosses is female parent like, those derived from double crosses analyzed by system cluster with 15 morphology traits can be divided into: some are three types: female parent like, intermediate and male parent like, some are only one type: male parent like obviously; ③ the growth of triple crosses' hybrids was small, some of those were dwarf, the growth of a same double cross' hybrids differed greatly, the highest hybrid was six times as the shortest one in a double cross.
