Maize Genetics Cooperation Stock Center Resources
The Maize Genetics Cooperation Stock Center maintains an extensive collection of maize genetic stocks. MaizeGDB supports the Stock Center by providing interlinked stock information throughout our database, as well as reports and catalogues of Stock Center stocks, and the ability to order stocks or request more information directly from the Stock Center.
The primary portal to genetic stocks (germplasm) is distributed by the Maize Genetics Cooperation Stock Center, Urbana IL. Additional germplasm may also be accessed from this site, for example germplasm with molecular or phenotype data represented in MaizeGDB. Many of these non-mutant resources, may be requested from the North Central Regional Plant Introduction Station (NCRPRIS).
The Stock Center Catalog is an extensive categorized listing of the stocks available from the stock center.
A key for how to Decrypt Stock Packet Labels is often helpful for researchers unfamiliar with the Stock Center's labelling practices.
You may also sort lines from the Ames Diversity Panel based on IBS (Identity by State) score using the TYPSimSelector.

What is a stock?
A stock is a sample of corn that expresses a specific variation (or a specific small set of variations). Thus, stocks are living examples of variation data.
