Germplasm Resources Information Network

Last updated

Germplasm Resources Information Network or GRIN is an online USDA National Genetic Resources Program software project to comprehensively manage the computer database for the holdings of all plant germplasm collected by the National Plant Germplasm System. [1]


GRIN has extended its role to manage information on the germplasm reposits of insect (invertebrate), microbial, and animal species (see sub-projects). [2]


The site is a resource for identifying taxonomic information (scientific names) as well as common names [3] on more than 500,000 accessions (distinct varieties, cultivars etc.) of plants covering 10,000 species; [4] [5] both economically important ones [3] and wild species. It profiles plants that are invasive or noxious weeds, [3] threatened or endangered, [3] giving out data on worldwide distribution [3] of its habitat; as well as passport information. [6] GRIN also incorporates an Economic Plants Database. [3]

The network is maintained by GRIN's Database Management Unit (GRIN/DBMU). [2] GRIN is under the oversight of National Germplasm Resources Laboratory (NGRL) in Beltsville, Maryland, [6] which in 1990 replaced its forerunner, the Germplasm Services Laboratory (GSL), [2] that had formerly run GRIN). [7] Since November, 2015 GRIN has been running on GRIN-Global software produced by a collaborative project between the USDA and the Global Crop Diversity Trust. [8]


A stated mission of GRIN is to support the following projects: [9]

<i>Pinus contorta</i> species of plant

Pinus contorta, with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines, it is an evergreen conifer.

Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research uses. These resources may take the form of seed collections stored in seed banks, trees growing in nurseries, animal breeding lines maintained in animal breeding programs or gene banks, etc. Germplasm collections can range from collections of wild species to elite, domesticated breeding lines that have undergone extensive human selection. Germplasm collection is important for the maintenance of biological diversity and food security.

<i>Dipteryx</i> genus of plants

Dipteryx is a genus containing a number of species of large trees and possibly shrubs. It belongs to the "papilionoid" subfamily – Faboideae – of the legume family (Fabaceae). This genus is native to South and Central America and the Caribbean. Formerly, the related genus Taralea was included in Dipteryx.

Uvaria is a genus of flowering plants in the soursop family, Annonaceae. The generic name uvaria is derived from the Latin uva meaning grape, likely because the edible fruit of some species in the genus resemble grapes.

<i>Hieracium albertinum</i> species of plant

Hieracium albertinum, known as western hawkweed or houndstongue hawkweed, is a species of the genus Hieracium that is very similar to Hieracium albiflorum with white flowers but differs in that the flower heads are clustered and the leaves, stems and bracts are covered in a thick layer of hairs. Standing 1 inch (3 cm) to 5 inches (13 cm) tall, it can be found blooming from June through August in forest clearings.
