| Abstract | The cultivated tomato (Solanum lycopersicum L.) is one of the most important vegetable worldwide. Cultivars have been bred using wild species genetic resources. The wild tomato species S. pimpinellifolium and S. lycopersicum var. cerasiforme are widely distributed in Ecuador. These species have been used in tomato breeding programs. We characterized them with microsatellite markers, using 23 microsatellite loci in 61 individuals of S. lycopersicum var. cerasiforme from three locations, and 25 microsatellite loci in 37 plants of S. pimpinellifolium from six locations. Morona Santiago (S. lycopersicum var. cerasiforme) and Manabi (S. pimpinellifolium) were the most variable populations. Populations of S. lycopersicum var. cerasiforme grouped into two clusters: one with individuals from Zamora Chinchipe, and the other with Morona Santiago s and Islas Galapagos individuals. The first cluster of the S. pimpinellifolium population individuals of the El Oro province and Islas Galapagos, while a second cluster included individuals from Manabi and the third cluster included (1)(2) National University of Loja, Small city “Guillermo Falconi Espinosa” La Argelia, Loja-Ecuador.
