利用美洲黑杨3个cv.和1个欧美杨cv.搭配成3个杂交组合。经11年试验研究,成功的选择出鲁×山,命名为辽宁杨(populus ×Liao ningnsis Z.Wang et H.D.Chen cv.nov));山×哈,命名为辽河杨(P.×Liao henica Z.Wang et H.D.Chen cv.nov);圣×山,命名为盖杨(P.×Gaixianesis Z.Wang et H.D.Chen cv.nov)。3个抗病速生新杂交种,目前已在我省栽植0.533万hm~2。7年生辽宁杨、辽河杨、盖杨材积生长分别比沙兰杨高120%,80%和110%。这3个新杂交种人工离体接种结果比沙兰杨发病率低69%~89%。木材气干密度和基本密度分别为沙兰杨的118%~150%和116%~135%,沙兰杨木材比重为0.309,3个新杂交种平均比重为0.389。
The use of three American black poplar cv. And a European and American Yang cv. Collocation into three hybrid combinations. After eleven years of experimental study, Lu Xishan was successfully selected and named Populus × Liao ningnsis Z.Wang et HDChen cv.nov); Mountain × Ha, named P. × Liao henica Z .Wang et HDChen cv.nov); St. X. Hill, named P. × Gaixianesis Z.Wang et HD Chen cv.nov. Three new fast-growing disease-resistant hybrids have now been planted in the province of 0.533 million hm ~ 2. 7-year-old Liaoning Poplar, Liaohe Poplar, Poplar Young volume growth respectively higher than Sallans Yang, 80% and 110%. The in vitro inoculation results of the three new hybrids were 69% -89% lower than those of Salmoneilla. The average dry density and basic density of wood were 118% -150% and 116% -135% of Salmynia cuniculata and 0.309 respectively. The average specific gravity of three new hybrids was 0.389.
