The following list of 1,160 accessions of wild Lycopersicon and related Solanum species is a revision
of the previous one, published in TGC vol. 51 (2001). Other types of TGRC stocks are catalogued in TGC 52
(monogenic mutants) and TGC 53 (miscellaneous genetic stocks). Inactive accessions have been dropped
and new collections added to the present list. The new material includes populations of L. chilense, L.
peruvianum, S. lycopersicoides, and S. sitiens collected in N. Chile in 2001, L. hirsutum and L.
pimpinellifolium accessions donated by Miguel Holle, and L. pimpinellifolium donated by Fernando Nuez.
Seed samples of most accessions are available for distribution, upon request, for valid research
purposes. Some accessions may be temporarily unavailable for distribution during regeneration. In general,
only small quantities of seed can be provided in most cases, 25 seed per accession for the self-pollinated
species, 50 for the outcrossers, and 5-10 for the tomato-like Solanum spp. and are intended to enable
researchers to produce seed in larger quantities to satisfy their own needs. Accessions are grown for seed
increase at UC-Davis, either in the field, for most of the selfing species, or in the greenhouse for the
outcrossers. Accessions of the former are increased in small plots with as few as 6 plants, whereas the latter
are regenerated from relatively large populations to maintain genetic variation.
For lack of space, only summary information on the collection site of each is presented here. To
facilitate choice of accessions, those comprising the core subsets for each species are identified with an
asterisk. More detailed passport information is available for each accession at our website
(http://tgrc.ucdavis.edu). Geographic coordinates (lat/lon) have been estimated for most accessions
collected from mainland S. America, and can be downloaded in several formats. Additional information will
be provided upon request.
