title: Genetic variation in Corynespora cassiicola: a possible relationship between host origin and virulence.
abstract: Genetic variation of 42 isolates of Corynespora cassiicola, a destructive fungal pathogen of many economically important crop plants including rubber, was investigated using RAPD-PCR analysis. Five genetic groups were identified using RAPD-PCR profiles generated by eight random primers. Results indicate that there is a significant genetic variation among C. cassiicola isolates collected from different host plants. These results should facilitate the development of rubber clones with enhanced resistance against all genetic groups of C. cassiicola.
