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 25 506 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.



NGBT Plant Germplasm System Distribution Policy

Plant germplasm is distributed to scientists, educators, producers and other bona fide research and education entities from National genebank of Tunisia active collection sites. The NGBT Curator and/or Research Leader will, in accordance with current NPGS policies and procedures, determine the legitimacy of a request when necessary.

Distributions to fulfill requests for repatriation of subsamples of germplasm collections to a country or community of origin, especially following natural or man-made catastrophes, are considered a high priority.

Although distributions for research, education, and repatriation are of the highest priority, the NPGS also encourages various seed-saver organizations and public gardens to conduct germplasm conservation activities that engage many individuals and groups throughout the country. Elements of the NPGS cooperate with seed-saver organizations and public gardens and may store germplasm for and distribute germplasm to such organizations.

Distribution of germplasm from NPGS collections to fulfill requests from individuals seeking free germplasm strictly for home use is generally considered an inappropriate use of limited resources and conflicts with U.S. Government policy of not competing with commercial enterprises. Requestors can be asked, in an appropriate manner, to justify the use of specific NPGS germplasm instead of suitable commercially available germplasm.

Accessions listed in the Germplasm Resources Information Network (GRIN) database as “not available” due to insufficient or low viability seed and/or scheduled for regeneration will generally not be available for distribution.

Other accessions are listed in GRIN as “not available” because they are not a part of the NPGS collection per se, but are conserved in NPGS genebanks to meet specific needs as described later in the section entitled “Categories of Germplasm Distributed and Availability.” In this category are certain accessions of improved germplasm that are only available from the owner/developer. Other accessions require that specific conditions be met by the requestor before distribution is possible.

NPGS sites will not distribute germplasm internationally when they cannot comply with the importation or quarantine requirements of the recipient country unless the requestor can provide a valid waiver of such requirements.
