Colletotrichum graminicola, the causal agent of anthracnose of sorghum, is a highly variable fungal pathogen. The high degree of variability hinders breeding for resistance and optimal deployment of cultivars. The extent and nature of this variability can now be characterized by random amplified polymorphic DNA marker analysis, a simple and fast technique that permits differentiation among isolates.
