NPGS Genebanks and NCPN Clean Plant Centers Joseph Postman Plant Pathologist & Curator National Clonal Germplasm Repository Corvallis, Oregon May 2010
U.S. National Plant Germplasm System (NPGS) Scope of Collections Pathogen Status (germplasm born pathogens) Plant Distribution (dilution of NCPN efforts?) How can NCPN benefit from NPGS
U.S. National Plant Germplasm System 441,000 Accessions 11,000 Species Germplasm Resources Information Network (GRIN) http://www.ars-grin.gov/npgs/
National Clonal Germplasm Repositories
Scope of NPGS Collections: Davis
Scope of NPGS Collections: Geneva Scope of NPGS Collections: Riverside
Scope of NPGS Collections: Corvallis
(5100 field plants, 7200 screenhouse plants) NCGR Corvallis – Collection Summary 10,500 total plant and seed accessions (5100 field plants, 7200 screenhouse plants)
ex situ clonal collections: Screenhouse Orchard
Repository Objectives Collect Maintain Evaluate Distribute
laboratory assay (ELISA, PCR) Virus Detection visual inspection biological assay laboratory assay (ELISA, PCR)
Virus Elimination Heat treatment Micropropagation
Known Infected Accessions
Plant Distribution 2009 521 requests received 5,800 items shipped
Full Pathogen Testing exceeds genebank capabilities
Priorities for Genebank Testing? Viruses that impact genebank management Pollen transmitted (Raspberry bushy dwarf, Blueberry shock) Accessions that are highly requested core accessions cultivars
Should we not distribute virus infected accessions?
Collaboration between NPGS and NCPN Introduction of NPGS accessions to nurseries is more efficient that foreign introductions. Include high-priority NPGS accessions in clean plant testing/clean-up. NPGS can safeguard obsolete NCPN accessions. ???
