Welcome to the Maize Genetics COOP

The Maize Genetics Cooperation
Stock Center is operated by USDA/ARS, located at the University of Illinois, Urbana/Champaign, and integrated with the National Plant Germplasm System (NPGS). We serve the maize research community by collecting, maintaining, and distributing seeds of maize genetic stocks. We also provide information about our stocks and the mutations they carry through the Maize Genetics and Genomics Database (MaizeGDB).
