ResumenMicrosatellite markers have been enough proved to be ideal markers to distinguish the fine-scale relationships within bean gene pools and between lines or populations in many species (Kwan and Gepts 2009, Diaz and Blair et al. 2006, 2007). They may help to reveal the history of bean introduction in the Iberian Peninsula and its widespread to other countries of the Mediterranean area. This research could help to give support, with experimental data derived from microsatellite polymorphisms to the existence of a new European genetic pool in common bean. Increasing the knowledge about the variability of the Mediterranean bean genotypes is essential in order to select the most suitable for breeding, both for hybridization and selection of lines, from populations. As well as this, it is quite important to gain a better understanding about what part of the genome of bean varieties from the New World are still present in nowadays Mediterranean bean varieties. With this aim, a set of microsatellite markers was analysed in a large and representative set of common bean populations of both American and European origins. Investigation of genetic similarity between populations from both continents made it possible to identify various types of American common bean introduced into Europe at different times or in different places and which have given rise to distinctive intermediate or recombinant types (Santalla et al. 2002).
