摘　　要：【目的】探讨黄淮地区大豆胞囊线虫(HeteroderaglycinesIchinohe)的种类及其分布。【方法】2001～2003年在黄淮大豆产区依据Riggs的鉴别模式对38个地点大豆胞囊线虫(SCN)生理小种作抽样调查,并结合文献资料,绘制出黄淮地区大豆胞囊线虫生理小种分布图。【结果】大豆胞囊线虫主要分布在山东、河北、北京、山西大部分地区、河南东部与北部、安徽北部;在山西南部及河南西南部地区的抽样调查中未检测到大豆胞囊线虫。其中1号生理小种主要分布在山东济南以南及以东地区,河南北部与河北南部交界地区,河南漯河、周口及安徽阜阳地区。4号生理小种主要分布在河南、山东、安徽交界地区,山西、北京地区,以及山东黄河三角洲地区。2号生理小种主要分布在山东聊城、德州地区,河北石家庄地区,河南焦作、获嘉地区。7号生理小种主要分布在山东半岛和河南开封、滑县、温县等地。5号生理小种在河南和河北有零星分布。另外,在河南商丘地区新发现有9号生理小种。【结论】黄淮地区的优势小种是1号和4号生理小种,抗线虫育种应该以兼抗1号和4号生理小种为主要目标。各生理小种的分布没有明显分界,优势小种分布区域中存在其他生理小种。在过去的10年中,该地区生理小种的组成相对稳定,本研究结果可供大豆抗线虫育种参考。[ Objective ] In order to investigate patterns and distribution of races of Soybean cyst nematode （SCN Heterodera glycines Ichinohe） [Method] A total of 38 sites in Huang-Huai valleys were sampled and identified for the distribution of soybean cyst nematode races during 2001- 2003. A map of race distribution was constructed according to the data from this experiment and literature cited. [Results] Three areas mainly infested with Race 1 were identified, i.e. the area south-east to Jinan in Shangdong Province, the area of northern Henan Province and its border region to south of Hebei Province, and the area of Luohe, Zhoukou of Henan Province and Fuyang of Anhui Province. Race 4 was predominant in Shanxi Province, Beijing and the adjacent area of Henan, Shandong and Anhui Provinces, and the delta of Huanghe River in Shandong Province. Race 2 was mainly in Liaocheng, Dezhou of Shangdong province and Shijiazhuang of Hebei province, and Jiaozuo and Huojia of Henan Province. Race 7 distributed in the west part of Jiaodong Peninsula of Shandong Province and Kaifeng, Huaxian, Wenxian of Henan Province. Race 5 was found and scattered in Hebei and Henan Province. Race 9 was found in Shangqiu of Henan Province, which was reported the first time in China. [Conclusion] From the above, Race 1 and Race 4 were the two predominant races in Huang-Huai valleys, which should be focused on for developing resistant cultivars. There might exist other races in an area with some predominant races. The race change in the past decade was not obvious, therefore, the results are meaningful to the present breeding for resistance to SCN in Huang-Huai valleys.
