In order to assess the genetic diversity and population structure of indigenous S. cerevisiae from Côte d'Ivoire, a total of 170 strains were isolated from four traditional alcoholic beverages through nine regions. Microsatellite analysis performed at 12 loci revealed that strains of palm oil and raffia wine were genetically related, unlike those of tchapalo and ron wine which formed two s from palm oil wine and raffia wine were clearly inbred. In comparison with the European, North American, Asian and others West African populations, Ivorian population was well defined, although most of these strains were admixed. Among these strains, only isolates from raffia wine appeared to have alleles in common to all populations. •Genetic diversity and structure of Saccharomyces cerevisiae population from Côte d'Ivoire were studied.•Ecological origin responsible for the phylogenetic relationship between S. cerevisiae strains•Inbreeding and outcrossing strains constitute population from traditional alcoholic beverages of Côte d'Ivoire.•Heterogeneity of populations from traditional alcoholic beverages of Côte d'Ivoire
