Not many historical or archeological records remain from the tomato journey from Solanum
pimpinellifolium (SP) to the vintage varieties, however, its domestication, migrations and
diversification in Europe can be unveiled using genetic analyses. The study of 628 SP, Solanum
lycopersicum var. cerasiforme (SLC), and Solanum lycopersicum var. lycopersicum (SLL) revealed: 1)
SP evolved into SLC during a migration from Peru and Ecuador, 2) there is a wild SLC Mesoamerican
population, 3) there are no wild SLC populations in Ecuador and Peru, 4) Peruvian and Ecuadorian SLC
are an admixture of Mesoamerican SLC and SP, 5) SP introgressions in SLC harbor flowering control
and light response genes, 6) at least some Mesoamerican SLL derives from domesticated Peruvian and
Ecuadorian SLC. A GBS analysis of 1,254 accessions,Postprint (published version
