引进２８个黑杨无性系进行造林试验。经过５年的观察，探讨了黑杨群体的年度遗传动态和性状间的遗传和表型相关，运用多性状综合评判技术进行综合评价，认为：Ｉ－１０７、Ｉ－１０８、Ｗ１－１４１、Ｍ－８０１０６和Ｃａｒｐｐａｃｉｏ５个无性系表现优良。
The introduction of 28 black poplar clones afforestation experiment. After five years’ observation, the genetic and phenotypic correlations between annual genetic dynamics and traits of Populus tomentosa were explored, and the comprehensive evaluation of the traits of I-107, I-108, W1-141, M -80106 and Carppacio five clones performed well.
