PEAR GENEBANK INFORMATION ON THE WORLDWIDE WEB

The US Department of Agriculture, Agricultural Research Service (USDA-ARS), National Clonal Germplasm Repository at Corvallis, Oregon houses the Pyrus genebank for the U.S. National Plant Germplasm System (NPGS). This collection includes about 700 European and 100 Asian cultivars.
In addition, the collection includes about 700 other clonal and seedlot representatives for the 26 major world taxa.
The clonal germplasm is maintained as field trees and is backed-up on site as potted plants growing under screen and as in vitro cultures stored for up to 5 years at 4°C. Seeds for wild species are preserved at -20°C. In addition, pear seeds and meristems are shipped to the National Seed Storage Laboratory in Ft.
Collins, Co., for long-term cryopreservation.
The background, or passport, information for each of the accessions is on the Germplasm Resources InfoNet (GRIN), which is accessible through the worldwide web at: http://www.ars-grin.gov/npgs or from the Repository homepage at: http://www.arsgrin.gov/ars/PacWest/Corvallis/ncgr.

An approved taxonomic list with authorities, citations, and synonyms is available from the website.
