GRIN both provides data, and compiles references to databases hosted by collaborating projects.

Plant Germplasm

The National Plant Germplasm System (NGPS) is a collaborative effort to safeguard the genetic diversity of agriculturally important plants. The mission of the NPGS is to support agricultural production by acquiring, conserving, evaluating, documenting, and distributing crop germplasm.

Animal Germplasm

Animal genetic resources underpin the livestock sector’s production and profitability. As a result livestock industries contribute billions of dollars to national economies. Our mission is to acquire, evaluate and preserve these strategic resources so that industry and the research community can have access to a broad array of genetic variability for national security, the introduction of genetic variation, corrective mating, and various research initiatives.

Microbial Germplasm

The goal of this program is to ensure that the genetic diversity of agriculturally important microorganisms is maintained to enhance and increase agricultural efficiency and profitability.The program will collect, authenticate and characterizepotentially useful microbial germplasm; preserve microbial genetic diversity; and facilitate distribution and utilization of microbial germplasm for research and industry.

GRIN Datasets

GRIN provides access to data maintained within its database, supporting both searches and export. The Rhizobium collection of nitrogen fixing bacteria is maintained by the ARS Soybean Genomics and Improvement Laboratory in Beltsville, MD. Plant Variety Protection Certificates are issued by the Plant Variety Protection Office of the USDA Agricultural Marketing Service.
