Abstract: The anthracnose is the main disease in bean production which is caused by Colletotrichum Lindemuthianum.It can reduce the output about 30% directly. Now the most appropriate and effective way to resolve the hard problem which is breeding disease-resistant varieties. In China, the race of Colletotrichum Lindemuthianum. Appears diversity, and the geographical distribution is more extensive and complex. The author investigated the Colletotrichum Lindemuthianum. Which were collected in 10 different areas in Liaoning with a view to determining the dominant race? Using the micro-single spore separation the strains, and were stored under 4 ℃ in test-tube slant on the PDA, and cultured in MA medium at 23 ℃.After 15 days, the study shows that these strins are all αrace.
