GSOR: Genetic Stocks Oryza Collection Home

The USDA Genetic Stocks – Oryza (GSOR) Collection at DBNRRC is part of the U.S. National Plant Germplasm System (NPGS) and serves as genebank and distribution center for genetic mutants and molecularly characterized genetic resources for the rice research community. GSOR was established in 2003 to give researchers who develop populations, often through grant funding, a place to deposit seeds of their genetic stocks and mapping populations. GSOR currently maintains ~33,000 accessions from 39 populations, of which about 70% were created by ARS scientists at DBNRRC. The GSOR program is responsible for storing, maintaining, documenting, and distributing (free of charge) these materials to the scientific community for genetic, genomic, and breeding efforts. Since 2003, GSOR has distributed 156,665 packets to rice research community resulting in a better understanding of the genetic control of traits for the development of new cultivars.

We request that the source of these rice accessions be acknowledged when used as a resource for research publications or cultivar development. Suggested acknowledgement: Rice accessions (Oryza sativa) were obtained from the USDA-ARS, Dale Bumpers National Rice Research Center, Stuttgart, Arkansas, Genetic Stocks Oryza Collection (www.ars.usda.gov/GSOR).
