GRIN: A Comprehensive Resource for Plant Taxonomy and Germplasm
Navigating the vast world of botanical classification requires precise data and reliable sources. The Germplasm Resources Information Network (GRIN) serves as a critical global resource for identifying taxonomic information, providing a bridge between common names and the rigorous scientific nomenclature used by botanists and agricultural scientists worldwide.
What is GRIN?
GRIN is an extensive database designed to track and identify plant varieties. It covers more than 10,000 species, encompassing both wild species and those of significant economic importance. The system manages data for over 500,000 accessions—which are distinct varieties or cultivars of plants—ensuring that researchers and conservationists have access to accurate biological records.

Scope of Botanical Data
Beyond basic identification, GRIN provides detailed profiles on various plant categories to aid in environmental management and conservation. This includes data on:
- Invasive and noxious weeds that may threaten local ecosystems.
- Threatened or endangered species requiring protection.
- Worldwide distribution and habitat data.
- Passport information, which provides the origin and collection details of a specific plant sample.
Additionally, the network incorporates a specialized Economic Plants Database, focusing on species that provide significant value to human industry and nutrition.
Administration and Technical Evolution
The network is maintained by the GRIN Database Management Unit (GRIN/DBMU). Oversight of the system falls under the National Germplasm Resources Laboratory (NGRL) located in Beltsville, Maryland. The NGRL took over these responsibilities in 1990, replacing the Germplasm Services Laboratory (GSL), which had previously managed GRIN.
To keep pace with modern data needs, the system underwent a significant technical upgrade. Since November 2015, GRIN has operated on GRIN-Global software. This software is the result of a collaborative effort between the United States Department of Agriculture (USDA) and the Global Crop Diversity Trust.

Frequently Asked Questions
What are plant accessions in the context of GRIN?
Accessions refer to distinct varieties, cultivars, or samples of plants that are cataloged within the database to maintain genetic diversity and taxonomic clarity.
Who manages the GRIN database?
The database is maintained by the GRIN Database Management Unit (GRIN/DBMU) under the oversight of the National Germplasm Resources Laboratory (NGRL).
What is the Economic Plants Database?
It is a specialized component of the GRIN network that profiles plants specifically valued for their economic utility.
What software does GRIN currently use?
Since November 2015, GRIN has utilized GRIN-Global software, created through a partnership between the USDA and the Global Crop Diversity Trust.
Does GRIN provide information on endangered species?
Yes, GRIN profiles plants that are threatened or endangered, providing data on their worldwide distribution and habitat.
