Taxonomic Information on Cultivated Plants in GRIN-Global




Introduction

The United States Department of Agriculture (USDA), Agricultural Research Service's (ARS) National Plant Germplasm System (NPGS) currently maintains over 600,828 accessions of mostly economically important vascular plants. It also coordinates the activities of more than 25 USDA and other seed and clonal germplasm sites and interacts with the international germplasm community and scientific public through the Germplasm Resources Information Network, GRIN-Global. The GRIN-Global database contains information on all genetic resources preserved by NPGS, including accessions of both domestic and foreign origin. Though the emphasis is on major, minor, or potential crops and their wild and weedy relatives, many other categories of plants are represented including ornamentals and some rare and endangered plants. A range of data--including passport, taxonomic, descriptor, observation, evaluation, and inventory data--for each germplasm accession is available in GRIN-Global. The taxonomic data providing the overall organization for germplasm accessions in GRIN-Global are the focus of these pages. For information on other aspects of GRIN-Global or NPGS see Janick (1989) or consult the NPGS home page.





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.
