摘　　要：以速生欧美杨中荷64号杨(Populus×euramericana"N3016")为母本、大青杨(Populus ussuriensis)为父本,经室内人工控制水培杂交获得F1代杂交种,在寒温带半干旱地区,经苗期筛选、无性系建立、品系评比到区域化试验示范等13年多地点多指标的测定,选育出杨树杂交新品种黑青杨(P.euramericana"N3016"×P.ussuriensis)雄性无性系。该品种干通直饱满,分枝角38.2°,11年生木材气干密度为0.35 g/cm3,纤维长宽比50.6。在齐齐哈尔地区11年生时单株平均树高、胸径和材积分别为14.8 m、16.2 cm和0.137 m3,分别超过对照品种小黑杨(P.simonii×P.nigra)8.4%、12.7%和33.3%。对杨灰斑病、锈病、烂皮病、溃疡病及青杨天牛(Saperda populnea)、白杨透翅蛾(Paranthrene tabaniformis)、树蜂等抗性较强。在北纬47°56'以南、最低温-36.4℃以上、降水量大于400 mm、无霜期120 d以上的自然条件下生长良好。F1 generation hybrids were obtained through controlled hydroponics hybridization indoors by taking P. euramericana （Dode） cv. ＇Zhonghe64＇ and Populus ussuriensis Kom. as female and male parent, respectively. By determining the multi-site and multi-index for 13 years within the selection at seedling stage, establishing clone, strain appraisals and re gionalization pilot demonstration, cloning new varieties of male, we selected Populus euramericana ＂N3016＂xPopulus ussuriensis. This variety is straight and full with the branching angle of 38.2%, and the air-dry density ＆ fiber aspect ratio of 11-year-old Populus euramericana ＂N3016＂ xPopulus ussuriensis are 0.35 g . cm-3 and 50.6, respectively. The average tree height, DBH and the volume of ll-year-old Populus euramericana ＂N3016＂ Populus ussuriensis in Qiqihar region are 14.8 m, 16.2 cm and 0.137 m3, respectively, which are 8.4%, 12.7% and 33.3% larger than that of the CK （Populus simoniixP. nigra）. Populus euramericana ＂N3016＂ xPopulus ussuriensis have stronger resistance on the main diseases （grey leaf-spot of poplar, poplar rust, Valsa sordida Nits., Botryosphaeria ribis （Tode） Grossenb. et Duggar） and the main boring beetles （Saperda populnea L., Paranthrene Tabaniformis and Siricidae）. Populus euramericana ＂N3016＂ xPopulus ussuriensis grew well under the condition of southern latitude 47°56＇, above minimum temperature of -36.4 ℃, precipitation of more than 400 mm, and above 120 d of frost-free period.
