摘　　要：采用国际通用的鉴别寄主法,鉴定连作条件下大庆和安达大豆胞囊线虫天然育种病圃生理小种和HG毒力类型。结果表明:生产条件下安达地区大豆胞囊线虫优势小种为毒力较强的14号生理小种,大庆地区为3号生理小种。室内盆栽鉴定安达试验基地HG类型为1.3.4.7,大庆试验基地HG类型为7。由于大豆胞囊线虫生理小种和毒力类型的组成日趋多样性,迫切需要发掘新的抗源和加紧培育水平抗性品种。The soybean cyst nematode（ Heterodera glycines） is an important constraint to soybean production in the world.Knowledge of the virulence phenotypes of soybean cyst nematode is crucial in choosing appropriate sources for breeding resistant varieties and managing the nematode. The objective of this study was to characterize the HG type and SCN race under continuous cropping in Daqing and Anda. The research results showed that： the SCN virulence type of Anda was HG type 1. 3. 4. 7（ race 14） and Daqing was HG type 7（ race 3）. It is urgent to explore new sources of resistance and breed horizontal resistance varieties because of diversity of virulence type of soybean cyst nematode.
