Revised List of Wild Species Stocks Chetelat, R.T. C.M. Rick Tomato Genetics Resource Ctr., Dept. Vegetable Crops, Univ. of California, Davis, CA  95616 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.   Acc. No. Collection Site Dept. / Prov.
