The USDA Genetic Stocks – Oryza (GSOR) Collection at DBNRRC is a subsite of the National Small Grains Collection (NSGC) and serves as distribution center for rice genetic mutants and molecularly characterized genetic resources that are important to the rice research community. These rice genetic stocks have been created using specialized techniques such as induced mutation and cross-breeding.  The GSOR program is responsible for storing, maintaining, documenting, and distributing (free of charge) these materials to the scientific community for use in genetic and genomic research. Ultimately these materials will aid in the understanding of the genetic control of traits that can be used to enhance the development of new cultivars that meet the needs of the U.S. rice industry.
