Abstract The genetic diversity and structure of horses raised in France were investigated using l l microsatellite markers and 1679 animals belonging to 34 breeds. Between-breed differences explained about ten per cent of the total genetic diversity Fst 0.099 . Values of expected heterozygosity ranged from 0.43 to 0.79 depending on the breed. According to genetic relationships multivariate and structure analyses breeds could be classified into four genetic differentiated groups .
