abstract: A total of 18 isolates of Collectotrichum graminicola infecting sorghum in Andhra Pradesh and Maharashtra, India, were characterised and compared for morphological, pathogenic and genetic diversity. The representative single-lesion isolates and their derivatives varied significantly for morphological traits -colony colour, growth pattern and sporulation on oat meal agar medium. These isolates also exhibited significant variation for disease reaction on a set of sorghum differential lines in greenhouse tests. The isolates from the local sorghum cultivars were although different from those of CSH 9, they did infect CSH 9 indicating a virulence shift in the C. graminicola population from the local sorghum to hybrid CSH 9. Genotypic variation was studied using the random amplified polymorphic DNA (RAPD) technique. A set of six random primers could differentiate the isolates. The cluster analysis indicated a very high genetic variability among isolates of C. graminicola and amogg variants from a single lesion isolates in RAPD profile.
