摘要
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 of Paranthrene tabaniformis and the relative resistance index of 49 poplar species or varieties（clones） to the pest were analyzed. The results revealed remarkable differences in the resistance to P. tabaniformis among the poplars;There were significantly differences among different cross combinations and different varieties of the same cross combination in resistance. Five varieties such as Jungar No. 1 （ 20 ）, Jungar No. 3, Nanlinl06 - Nanlinl05, riploid Populus tomentosa showed high resistance to P. tabaniformis, Populus nigra showed high susceptibility and P. deltoids x P. deltoids,P, euphratica showed medium susceptibility.
