大豆包囊线虫(SCN Heterodera glycines Ichinohe ) 是在中国的最重要的全国性的大豆疾病之一。在区域的 38 土壤样品或地点的一个总数为 SCN 被取样并且测试赛跑在期间 2001 2003 为在 Huang-Huai 山谷的赛跑分发的检查。赛跑分发的一张地图从现在的学习和引用的出版报告根据数据被构造。三个区域,也就是到在 Shangdong 的 Jinan 的东南的区域省;到 Hebei 省的南方的北河南省省和它的边阶区域的区域;并且 Luohe 的区域,河南省省的 Zhoukou 和主要与种族 1 大批出没于的安徽省的 Fuyang 被识别。种族 4 在山西省,北京和河南省,山东,和安徽的邻近的区域是占优势的在山东的 Huanghe 河的省,和三角洲省。种族 2 主要在河南省省的 Liaocheng, Shangdong 省的 Dezhou 和 Hebei 省的 Shijiazhuang 被发现。种族 7 在山东省和 Kaifeng 的 Jiaodong 半岛的西方部分被散布, Huaxian,河南省的 Wenxian 省。种族 5 在 Hebei 和河南省省被发现并且散布。种族 9 在河南省省的 Shangqiu 被发现,它在中国第一次被报导。种族 1 和种族 4 是在 Huang-Huai 山谷的二占优势的赛跑,这能被看见,并且那研究应该集中于开发这些赛跑的抵抗栽培变种。可能在那里存在在有一些占优势的赛跑的一个区域的另外的赛跑。因此,十年不是的在过去的赛跑替换显然发现结果应该对未来在 Huang-Huai 山谷为抵抗繁殖到 SCN 有意义。
Soybean cyst nematode (SCN Heterodera glycines Ichinohe) is one of the most important nationwide soybean diseases in China. A total of 38 soil specimens or locations in the area was sampled and tested for SCN races during 2001-2003 for the inspection of race distribution in Huang-Huai Valleys. A map of race distribution was constructed according to the data from both the present study and the published reports cited. Three areas, namely, the area of southeast 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 mainly infested with Race 1 were identified. 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 found in Liaocheng, Dezhou of Shangdong Province and Shijiazhuang of Hebei Province, and Jiaozuo and Huojia of Henan Province. Race 7 was 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 for the first time in China. It can be seen that Race 1 and Race 4 were the two predominant races in Huang-Huai Valleys, and that research should focus on developing resistant cultivars of these races. There might exist other races in an area with some predominant races. The race substitution in the past decade was not obviously found, therefore, the results should be meaningful to future breeding for resistance to SCN in Huang-Huai Valleys.
