The C.M. Rick Tomato Genetics Resource Center (TGRC) is a genebank of wild relatives, monogenic mutants and
miscellaneous genetic stocks of tomato. The wild species group includes representatives of all nine Lycopersicon species, as
well as 4 related Solanum species. The monogenic mutants include spontaneous and induced mutations affecting many
aspects of plant development, introgressed disease resistance genes, and protein marker stocks.
|
The miscellaneous group
includes linkage tester stocks, trisomics, translocations, landraces, and several types of prebreds (e.g. alien additions,
segmental substitution lines, etc.).
The collection was founded by Dr. Charles M. Rick in the Dept. of Vegetable Crops, UC-Davis, who collected many of
the wild species accessions and produced a large number of marker and cytogenetic stocks.
|
Over the years, many other
researchers contributed germplasm to the TGRC, creating what is now regarded
as the world's most comprehensive collection of genetic stocks and wild
relatives of tomato.
The TGRC is part of the National Plant Germplasm
System (NPGS), from which it receives partial financial support. Additional funding is
provided by the University of
California, an endowment, and grants from the California Tomato Research
Institute and the California Tomato
Commission.
