Grassland ecosystems: an outlook into the 21st century: proceedings. Piracicaba: SBZ: FEALQc2001  ap. 232-234.  a(ID n. 05-02)  aThis work animed to determine the genetic diversity of colletrotichum gloeosporoides infecting Stylosanthes spp. in Brazil, China and India. A total of 132 isolate originating from S. seabrana, S. macrocephala S. scabra. S. scabra and S. guinensis were used. Four major genetic group were identified from an analysis of genetic diversity using selection-neutral DNA markers. Group I contained 20 isolates and this may represent genotype that migrated from the center of diversity in Brazil and Colombia to Australia. Thailand and India. Group 2 consisted of 66 Brazilian isolates and group 3 had 19 isolates from Australia, Burundi, Brazil, China, Colombia, Ivory Coast and Peru. The 27 isolates in group 4 were very diverse with&gt50% dissimilarity between some isolates. Genetic diversity in Brazil and China was more extensive than in the Indian pathogen population.  aanthracnose  aBrazil  aChina  agenetic variation  aIndia  aplant pathology  aStylosanthes  aAntracnose  aCerrado  aVariação Genética  aAnthracnosis  aBrasil  aEstilosantes  aFitopatologia1 aCHAKRABORTY, S.1 aFERNANDES, C.
