摘要
对来自安徽灵璧县虞姬乡的大豆根腐病的土壤样品进行了病原分离和鉴定。经诱捕分离,从发病田块的土壤和发病植株上共分离到3株大豆疫霉菌株;采用特异性PCR检测,结果表明分离物为大豆疫霉;生理小种测定表明,3个菌株的毒力结构与已经报道的大豆疫霉菌株不同。
Three isolates（BLPS1, BLPS2 and BLPS3） were isolated from soil, and identified as phytophthora sojae Kanfman ＆ Gerdemann. And isolates were detected by a rapid and specific PCR. By using the method of hypocotyls inoculation on 14 different hosts, BLPS1, BLPS2 and BLPS3 were identified as new races. This research will provide useful information about breeding and using resistant varieties.
