“…These new forms could have subsequently been disseminated to other parts of Europe, contributing to much-wider variation observed in the current European germplasm (Lioi, 1989;Gil and De Ron, 1992;Escribano, De Ron and Amurrio, 1994;Limongelli, Laghetti, Perrino, and Piergiovanni, 1996;Zeven, 1997;González, Monteagudo, Casquero, De Ron and Santalla, 2006). Therefore, the Iberian Peninsula, mainly the north and northwest regions, could be considered as a secondary center of genetic diversity for the common bean crop, especially regarding the large white-seeded cultivars (Santalla et al, 2002;Rodiño et al, 2006).…”
