摘　　要：通过对21个大豆疫霉根腐病菌株进行鉴定,共鉴定出6个生理小种,即1、3、9、11、17、21号生理小种,其中54%的菌株为1号生理小种,表明1号生理小种仍是黑龙江省的优势生理小种。同时对346份黑龙江省大豆种质进行了大豆疫霉根腐病的抗病性鉴定与评价,鉴定出抗疫霉根腐病的资源15份,占供试材料的4.3%;中抗材料12份,占供试材料的3.5%;其它材料均为感病,占供试材料的92.2%。结果表明黑龙江省大豆疫霉根腐病抗性资源较少。Six races including race 1,3,9,11,17,21,were identified by 21 strains of Phytophthora sojae.The 54% of them were race 1,which was the main race in Heilongjiang province.At the same time,the resistance of 346 soybean germplasm from Heilongjiang province to phytophthora root rot were identified and evaluated,15 resistant germplasm were identified,which accounted 4.3% of the tested materials;12 moderate resistant germplasm were identified,which accounted 3.5% of the tested materials;the others were susceptible,which accounted 92.2%.The results showed there were few resistant germplasm in Heilongjiang Province.
