摘　　要：对来源于黑龙江、吉林、内蒙古、河北、云南等8个省(市)的15个菜豆炭疽菌分离物进行生理小种鉴定,鉴别出5个菜豆炭疽菌生理小种,其中81号小种出现的频率高达67%,是中国的优势小种。用81号小种对181份菜豆进行抗性鉴定,发现高抗材料2份,抗病材料43份,高感材料33份,说明我国菜豆种质资源对炭疽菌81号小种抗感差异显著,抗病资源丰富。Fifteen isolates of Colletotrichum lindemuthianum from 8 provinces including Heilongjiang, Jilin, Inner Mongolia, Hebei,Yunnan etc. were identified and 5 races were discovered. Among them the race 81 is the prevalent race in China and the frequency reached 67%. Of the 181 common bean accessions, 2 are highly resistant, 43 are resistant and 33 are highly susceptible to the race 81. It indicated that there are notable differences between the accessions in the resistance to the race 81 and the resistant germplasm is very abundant in Chinese common bean.
