摘　　要：杨树锈病近年来在江苏一些地区发生严重。为了解不同杨树无性系对锈病的抵抗能力，2008年9—10月对江苏省泗洪县境内部分杨树无性系抗锈病能力进行了观察。观察结果表明，‘L35’杨抗病性较强，‘NL-95’和‘NL-895’抗病性中等，‘NL-80351’、‘中林46’、‘NL-107’等发病严重。提出在没有选育出更抗锈病，更适合在江苏北部地区种植的杨树新无性系以前，种植‘L35’、‘NL-95’和‘NL-895’是解决杨树锈病较好的办法。Poplar rust occur seriously in recent years in some areas of Jiangsu province. In order to understand the different clones of poplar＇s （Populus deltoides and P. x euramericana） resistance to the rust disease, the anti-rust ability of different poplar clones were observed in 2008 from September to October in Sihong county. The observation results showed that the poplar clone ＇ L35＇ was strongly resistant to the disease, clone ＇ NL-95＇ and ＇ NL-895＇ were medium resistance, and clone ＇ NL-80351 ＇ , ＇ Zhonglin 46＇ , ＇ NL -107＇ were seriously affected. The paper proposed that planting clone ＇ L35＇ , ＇ NL - 95＇ and ＇ NL-895＇ was a better solution to poplar rust in northern of Jiangsu province before a new clone was bred out.
