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，其中一个组合的苗高最高与最低相差达６倍
In this paper, black-white poplar crosses were conducted on 21 cross combinations of 8 Populus genotypes and 5 Populus genotypes. The results showed that: (1) seedlings were not obtained in single cross combinations, seedlings were obtained in 20% cross combinations and 67% double cross combinations; (2) The system of cluster analysis of traits, and some can be divided into three categories: partial mother type, intermediate type, partial parent type, and some obvious partial parent type; ③ three cross combination obtained seedling growth is small, and some For the dwarf-shaped, the same double cross combination of seedlings grown very different, one of the highest and lowest seedling height difference of up to 6 times
