摘　　要：由大豆疫霉菌引起的大豆疫霉根腐病是严重影响大豆生产的毁灭性病害之一。防治该病经济有效的方法是抗病育种,而抗性资源筛选又是抗病育种的基础。采用下胚轴伤口接种法,用黑龙江省大豆疫霉菌的1号优势生理小种对来自黑龙江、吉林、河南、内蒙古、辽宁、湖北、四川、河北、陕西、中国农业科学院的536份栽培大豆材料(其中农家品种280份、其它大豆品种256份)进行抗性鉴定,抗病的152份,占28.3%,中间类型的135份,占25.2%,感病的249份,占46.5%。280份农家品种中,抗病的有89份,占农家品种的32%,这说明农家大豆品种资源抗性比例较高。种皮色或种脐色为黄色或褐色的材料中抗性种质较多。Phytophthora root and stem rot caused by Phytophthora sojae is a destructive disease in soybean production regions all around the world. Utilization of resistant variety is the most economical and environmentally safe method for controlling the disease,and it is the basement for resistance breeding. 536 soybean germplasms（including 280 native soybean varieties） from Heilongjiang,Jilin, Henan, Liaoning, Hubei, Sichuan, Hebei, Shannxi, Chinese Academy of Agricultural Sciences were inoculated with race 1 of Phytophthora sojae,which is the superiority race in Heilongjiang Province. The results showed the resistant, intermediate and susceptible ones were 152,135 and 249,and accounted for 28.3%,25.2% and 46.5%,respectively. Among the 280 native soybean varieties,eighty-nine （accountEd for 32%） were resistant. The results suggest that native soybean varieties are more resistant to Phytophthora sojae, and there is more resistance germplasm in soybean with yellow hilum or brown seed coat.
