摘　　要：为选育出适合辽宁中南部地区推广栽植的速生抗逆杨树新品种,对引进到辽宁的欧美杨111无性系进行引种试验研究。该研究以中辽1号杨为对照,通过无性系苗期测定、多点区域生长对比试验、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111。在辽宁绥中县,8年生欧美杨111平均胸径28.29 cm,平均树高19.5 m,平均单株材积0.577 m^(3),分别超过对照种中辽1号杨18.12%、11.43%和36.08%,表现出明显的速生优势。同时该品种还具有抗病性强、干形好、易繁殖、材质优良等特点,可作为辽宁中南部地区推广应用的高产抗病杨树新品种。In order to breed a new poplar variety with fast growth and strong stress resistance suitable for planting in Mid-southern of Liaoning,an experimental study was carried out on the introduction of P.×euramaricana‘Bellotto’clone introduced in Liaoning.Taking P.×canadensis cv.‘zhongliao1’as the contrast,through the clone seedling stage determination,multi-point growth comparison test,disease-resistance evaluation,wood and pulping properties test,finally selected fast-growing,strong disease resistant new poplar variety P.×euramaricana‘Bellotto’.Such as in Suizhong,Liaoning province,the average diameter of 8-year-old P.×euramaricana,‘Bellotto’was 28.29 cm,the average height that of was 19.5 m,and the average volume per plant was 0.577 m^(3)which were 18.12%,11.43%and 36.08%higher than that of CK P.×canadensis cv.‘zhongliao1’,respectively.Moreover,this variety also had the characteristics of strong disease resistance,good stem shape,easy propagation,good wood properties and so on.As the new poplar variety with high-yield and disease-resistant,P.×euramaricana‘Bellotto’was especially suitable to be planted in central and southern part of Liaoning.
