The NGRP acquires, characterizes, conserves, documents, and distributes to scientists germplasm of all life forms important for
food and agricultural production. The Germplasm Resources Information Network (GRIN) documents these animal, microbial, and plant
collections through informational pages, searchable databases, and links to USDA-ARS projects that curate the collections.
GRIN is operated by the USDA-ARS National Germplasm Resources Laboratory in Beltsville, MD.
