Abstract:

In this article, we obtained 30 separate strains from Brazil soybean, and identified four Colletotrichum isolates by morphological and molecular biology method, which were Colletotrichum gloeosporioide, Colletotrichum capsici, Colletotrichum truncatum and Colletotrichum dematium. This study was proved that Colletotrichum had rich diversity in Brazil soybean, because the four Colletotrichum isolates separated from 30 isolates belong to different species, and it could not only enrich the soybean databank and strain resource, but also provided reference for plant quarantine.
