摘　　要：为解决江淮地区杨树主栽品种少、部分品种退化、林分结构稳定性较差、人工林生产力低下、飞絮现象严重等问题,安徽省林业科学研究院杨树课题组历经18年研究,通过亲本选择、杂交、苗期选择和多点田间测试,结合速生性、丰产性、抗病性、木材品质、纸浆造纸性能等指标综合评价选育出两个杨树优良新品种(无性系),即‘江淮1号杨’和‘江淮2号杨’。其具有速生、干形通直圆满、适应性强等遗传特点和出材率高、材质佳,且具较强的抗病虫、抗风和耐水湿性能,不仅适合在安徽省沿江、江淮、淮北平原栽植,也可在长江中下游至黄河以南平原区推广。In order to address such problems as poor selection of main planting poplar cultivars,degradation of some poplar cultivars,poor stability of some poplar stands,low productivity of some poplar plantations and serious and disturbing flying of flocculent poplar seeds,2 new fine poplar cultivars(clones),namely Jianghuai Poplar No.1 and Jianghuai Poplar No.2,have been developed by the poplar study group with Anhui Academy of Forestry,through a 18-year-long study,including selection of parents,hybridization,selection in the seedling stage and multiple-site field tests,as well as a comprehensive assessment of the fast-growth,yield increase,disease resistance,wood quality and pulp papermaking performance.The 2 fine poplar clones have such genetic properties as fast growth,straight and rounded trunk and high adaptability,and good features including high lumber recovery,good wood quality,high resistance to diseases,pests and wind and water tolerance,suitable not only for planting in areas along the Yangtze River Anhui section,Jianghuai Region and Huaibei Plain,but also for promotion in the plain areas between the middle and lower reaches of the Yangtze River and south of the Yellow River.
