An adequate characterization of fruit tree species genotypes allows to optimize their yield in different environmental conditions, as well as their proper use in breeding programs. Molecular based tools are a highly reliable approach to characterize plant material, both for homonymy and synonymy detection and for the study of genetic diversity. In this work, two specific zones have been studied in the province of Málaga, where local apple and peach genotypes with low chilling requirements are still grown. These genotypes were identified with microsatellite markers and the existing genetic diversity was analysed. The data were compared with apple and peach genotypes from other regions and countries maintained in germplasm collections. The results indicated that, in apples, there is not a clear difference between the local material studied and the germplasm material. However, a group of differentiated local genotypes has been detected for this species, whose conservation could be interesting since they are grown in coastal areas with minimal chilling requirements. In the case of peach, there is a group of very similar local genotypes. This group is highly endangered due to the increasing cultivation of foreign varieties
