Summary This study was conducted to evaluate the genetic diversity of Blonde d’Aquitaine, a well‐muscled native French beef breed, and to understand the relationships between Blonde d’Aquitaine, Limousin and Salers. We also compared these three beef breeds to the Holstein dairy breed. For this purpose, a set of 16 microsatellite markers were investigated. The obtained results show that Blonde d’Aquitaine has a high level of genetic diversity. Our study shows also that the French beef breeds have genetic differentiation among them, with approximately 9% of the total variation owing to breed differences. Our results show also that Blonde d’Aquitaine and Salers populations are genetically more similar to each other than to the Limousin.
