对49个杨树种、品种(无性系)的白杨透翅蛾Paranthrene tabaniformis Rott.危害指数和相对抗性指数进行了调查和分析,结果表明对白杨透翅蛾的抗性表现出很大的差异,大部分表现出一定的抗性,不同杂交组合的相对抗性指数差异显著,同一杂交组合的不同品种(无性系)间抗性也存在显著差异。准噶尔1号20、准噶尔3号、南林106-南林105、96号杨K15、三倍体毛白杨等5个品系为高抗品系。欧洲黑杨为高感品系,创新杨、胡杨为中感品系。
The damage index and relative resistance index of Paranthrene tabaniformis Rott. From 49 poplar species and cultivars (clones) were investigated and analyzed. The results showed that there were great differences in the resistance of Populus toona , Most showed some resistance. The relative resistance index of different hybrid combinations was significantly different. There was also significant difference among different varieties (clones) of the same hybrid combinations. Five strains of Zungarl 20, Junggar 3, Nanlin 106-Nanlin 105 and 96 Yang K 15 and Triploid Populus tomentosa were highly resistant strains.
