摘　　要：对新引进到辽宁的欧美杨177无性系进行引种试验研究。以中辽1号和赤峰杨为对照,通过无性系苗期测定、多点生长对比试验、抗病性评价、材性及制浆造纸性能测试等,最终选育出速生、抗病性强杨树新品种欧美杨177。在辽宁黑山,9年生欧美杨177平均胸径22.27cm,平均树高17.2m,平均材积0.379m^(3),分别超过中辽1号18.77%、16.22%和36.82%。其总叶面积大,速生期内净光合速率较高,表现出优良的幼苗生长性状,且对杨树叶锈病具有高度抗性。同时该品种还具有干型好、易繁殖、材质优良、适应性广等特点,是适合于辽宁中南部地区推广应用的高产抗病杨树新品种。An experimental study was carried out on the introduction of Populus.×euramaricana‘177’clone introduced to Liaoning.Take P.×euramaricana cl‘zhongliao1’and P.×xiaozuanica cv.‘Chifeng’as the controls,through the clonal seedling stage determination,multi-point growth comparison test,disease-resistance evaluation,wood and pulping properties test,finally selected fast-growing,strong disease resistance,new poplar variety P.×euramaricana‘177’.Such asin Heishan of Liaoning province,the average diameter of the 9-year-old was 22.27cm,the average height of the tree was 17.2m,and the average volume per plant was 0.379m^(3),respectively 18.77%,16.22%and 36.82%higher than CK P.×euramaricana cl‘zhongliao1’.The total leaf area was large and the net photosynthetic rate was higher during the rapid growth period,showed excellent seedling growth characteristics,and that had high-resistance to poplar leaf-rust.The new selected variety also had the characteristics of trunk well,easy reproduction,good wood properties and wide-ranging adaptability.As the new poplar variety with high-yield and disease-resistant,P.×euramaricana‘177’is especially suitable to plant in Mid-southern of Liaoning.
