Boyacá is one of the departments of Colombia pioneer in the national production of deciduous, especially peaches, plums, pears and apples. Eight Random Amplified Microsatellite primers (RAMs) were evaluated in eleven apple (Malus communis), seven pears (Pyrus communis), two apricots (Prunus armeniaca L.) and one almond (Prunus amigdalus L.) materials from deciduous collection of the Pedagogical and Technological University of Colombia. A total of 128 bands were generated with molecular weights ranging between 250 and 1300 Kb. Two groups and subgroups were formed, a similarity coefficient of 0,55, according to specie and fruit characteristics. The number of polymorphic loci ranged between 96 and 123 for CGA and ACA primers, respectively. The average value of heterozygosity was 0,34, much lower than values found in other genetic diversity studies in the genus Malus and Pyrus. Similarity index and genetic distances corrobate the synteny between these genomes which can be taken advantage for identifying of genes, comparative mapping and interspecific hybridization.
