Vegetable Crops, Univ . of California, Davis, CA   95616 The following list of 1,131 available accessions of wild Lycopersicon and related Solanum species is a revision of the previous list issued in TGC 48 (1998) .   Extinct or temporarily unavailable accessions have been dropped and new collections have been added .   Recent additions to this list include the following items:   L . esculentum var . cerasiforme populations collected by D . de Zerpa in Venezuela, L . cheesmanii and L . pimpinellifolium from the Galapagos Islands (J . W . Rick), L . hirsutum f . glabratum from Ecuador (M . Coffey), L . peruvianum , L . pimpinellifolium , and L . hirsutum from Peru (M . Holle), L . parviflorum from Ecuador (F . Nuez), L . peruvianum and L . pimpinellifolium selections resistant to CMV and TYLCV, respectively (C . Caranta, A . Moretti), and S . lycopersicoides and S . juglandifolium PI lines transferred from the USDA . All accessions have been grown for seed increase at UC - Davis and seed samples are available for research purposes .   Accessions of the outcrossing species (or races) are regenerated in such a way as to maintain intrapopulation genetic variation, and may segregate for traits of interest, therefore larger seed samples are provided .   Our seed supplies of the four Solanum spp . tend to be limited, yet small samples will be provided to interested researchers .   Members of the core collections for each species are identified below with an asterisk in order to assist selection of specific accessions for seed requests .    Detailed passport information on each accession can be obtained from our website ( http://tgrc . ucdavis . edu ), with additional information available on request .   Latitude and longitude coordinates for wild populations are currently being recorded in the TGRC database; to date, the coordinates of all collections from Chile have been entered, and work on Peru and other countries is in progress .
