Variation for nine virulence and four electrophoretic characters was determined for 69 samples of Colletotrichum gloeosporioides collected in five natural stands of its host, Stylosanthes guianensis, in South America. Virulence phenotypes varied from four in the Quilichao population to 22 in the ...
