Conteúdo: | The genetic structure of Mycosphaerella fijiensis populations around the world was examined using DNA restriction fragment length polymorphism (RFLP) markers. Allele frequencies at 19 nuclear RFLP loci were estimated in a sample of 136 M. fijiensis isolates from five geographicalpopulations representative of banana-producing areas (South-east Asia including the Philippines and Papua New Guinea, Africa, Latin America and Pacific Islands). Within each population, gemetic disequilibrium tests between the 19 nuclear RFLP loci were mainly non significant (P>0.05), indicating that random sexual reproduction occurred in these populations. All M. fijiensis populations had a high level of gene diversity were found in the two South-East Asian populations (H: 0.57 and 0.59). Most of the alleles (>88%) detected in Africa, Latin America and Pacific Islands populations were also detected in South-East Asian populations.
