摘要
利用国际上通用的一套标准鉴别品种，对采自中国农科院昌平基地大豆试验田的大豆孢囊线虫群体进行了生理小种鉴定。温室盆栽鉴定和塑料钵柱鉴定结果表现一致，各个鉴别品种根部都着生较多的孢囊，孢囊指数最低为４９．８％，对孢囊线虫的反应极明显地全部表现为（＋）。按Ｒｉｇｇｓ和Ｓｃｈｍｉｔｔ（１９８８）的划分标准，该线虫群体为４号生理小种。这一结果极有力地证实北京地区有４号生理小种分布。
Abstract Using a set of standard differentials of Golden et al. (1970), we determined the race type uf soybean cyst nematode population collected from Changping experimental base of CAAS in suburban Beijing. The results identified in clay pots and in plastic bags (20 ×4.5 cm) indicated the reactions on every differential were significantly (+). According to the classfication scheme by R. D. Riggs and D. P. Schmitt (1988) this population is race 4 of soybean cyst nematode. Which strongly verified that there is race 4 of soybean cyst nematode distributed in suburban Beijing.
