Resumen:
Wild tomatoes are native of western South America, distributed from Ecuador to northern Chile, and with two endemic species in the Galápagos Islands (Darwin et al. 2003; Peralta & Spooner 2005; Peralta et al. 2005). They grow in a variety of habitats, from near sea level to over 3,300 m in elevation, in arid coastal lowlands and adjacent hills or “lomas” where the Pacific winds drop scarce rainfall and humidity; in isolated valleys in the high Andes, and in arid regions like the severe Atacama Desert in northern Chile. Andean geography, diverse ecological habitats, and different climates have all contributed to wild tomato diversity (Figure 1). A recent taxonomic revision of the tomatoes and their relatives (Peralta et al. 2007) provides new species definitions, illustrations, descriptions and distributions, revises and updates the nomenclature, summarizes several morphological and molecular studies and discusses phylogenetic relationships.
