Technical Abstract: Wild tomatoes are tremendous sources of useful traits in tomato breeding, to improve disease resistances, environmental tolerances, and improved agronomic traits such as increased soluble solids. This chapter includes historical and updated information on the phylogenetic relationships of wild tomatoes to aid breeders in the use of this germplasm. We recognize 13 species of wild tomatoes (Solanum arcanum Peralta, Solanum cheesmaniae (L. Riley) Fosberg, Solanum chilense (Dunal) Reiche, Solanum chmielewskii (C.M. Rick, Kesicki, Fobes & M. Holle) D.M. Spooner, G.J. Anderson & R.K. Jansen, Solanum corneliomulleri J.F. Macbr., Solanum galapagense S. Darwin & Peralta, Solanum habrochaites S. Knapp & D.M. Spooner, Solanum huaylasense Peralta, Solanum lycopersicum L., Solanum neorickii D.M. Spooner, G.J. Anderson & R.K. Jansen, Solanum pennellii Correll, Solanum peruvianum L., Solanum pimpinellifolium L..), and four closely related wild species (Solanum juglandifolium Dunal, Solanum lycopersicoides Dunal, Solanum ochranthum Dunal, Solanum sitiens I.M. Johnst.). The species of tomatoes have been treated quite differently by different authors. Recent cladistic and phenetic studies of species boundaries and relationships within the tomatoes and wild relatives have used a combination of molecular and morphological data. We divide the 13 species of wild tomatoes into 13 informal species groups.
