Taxonomic Information on Cultivated Plants in GRIN-Global




Summary

The National Plant Germplasm System of the Agricultural Research Service, U.S. Department of Agriculture maintains a computer database, the Germplasm Resources Information Network, GRIN-Global, for the management of and as a source of information on its 600,828 germplasm accessions. The taxonomic portion of GRIN-Global provides the classification and nomenclature for these genetic resources and many other economic plants on a worldwide basis. Included in GRIN-Global Taxonomy are scientific names for 27,944 genera (14,734 accepted), 1,422 infragenera (1,350 accepted), and 126,038 species or infraspecies (69,269 accepted) with common names, geographical distributions, literature references, and economic importance. Generally recognized standards for abbreviating authors' names and botanical literature have been adopted in GRIN-Global. The scientific names are verified, in accordance with the international rules of botanical nomenclature, by taxonomists of the National Germplasm Resources Laboratory using available taxonomic literature and consultations with taxonomic specialists. Included in GRIN-Global Taxonomy are federal- and state-regulated noxious weeds and federally and internationally listed threatened and endangered plants. Since 1994, GRIN-Global taxonomic data have been searchable on the Internet.





The NPGS distributes plant germplasm to professional scientific research individuals and organizations, and verified plant breeders. Requests from producers and educators will be considered on a case-by-case basis, but only when NPGS germplasm that is not readily available from commercial sources is a justified requirement. NPGS germplasm is not available for individual, home, or community gardening. Requests to support educational objectives are typically considered only for college-level projects. Please view the short video on the NPGS for more details.
