Genetic stocks are useful tools both in applied plant breeding, such as locating traits in relationship to other traits with an identified marker, for speeding up research cycles with early-flowering mutants, and in basic genetic studies for determining gene location and function. Genetic stocks collections help preserve materials that otherwise might be lost as researchers retire and/or grants terminate. Model genetic stocks collections in the US have been set up in tomatoes, maize, barley, and wheat. In August 2003, the Genetic Stocks - Oryza (GSOR) was established at the USDA-ARS Dale Bumpers National Rice Research Center, at Stuttgart, Arkansas.
The GSOR will include materials produced at Stuttgart such as dominant and recessive male sterile mutants, various morphological mutants, cytogenetic tools such as trisomics and telotrisomics, and an RIL set of about 350 F10 lines from the cross Kaybonnet lpa1-1/Zhe 733. Materials produced by cooperators, including other USDA-ARS units, universities, industry, and some NSF-supported projects, will also become part of the GSOR. The GSOR collection will make seeds and information for each stock available through GRIN to US and international rice researchers. The respository homepage (url = http://www.dbnrrc.ars.usda.gov/gsor) will be maintained and will facilitate disseminating information about the collection contents.
