| 摘 要： | 在生产条件下，高抗大豆抗孢囊线虫３号生理小种的抗线１号、抗线２号，在同一块地连续种植４－５年，明显发病。病土采用盆栽法，应用五个标准鉴定品种：Ｐｉｃｋｅｔ、Ｐｅｋｉｎｇ、ＰＩ８８７８８、ＰＩ９０７６３、Ｌｅｅ（Ｇｏｌｄｅｎ１９７０）及抗线２号，重新进行生理小种鉴定。按Ｒｉｇｇｓ（１９８８）标准，原来的３号生理小种线虫群体致病性发生变异，出现１４号生理小种。

| Abstract: | Under production condition, Kangxian No.1 and No.2 were planted by continuing 4-5 years in the pot culture with diseased siol. Five standard varieties: Pickett, Peking, PI88788, PI90763, Lee (Golden 1970) and Kangxian No.2 were used to identify race, according to riggs (1988) standard, pathogenicity of the old race No.3 was changed. Race No.14 was found. |
