  1. NPGS GenebanksandNCPN Clean Plant Centers Joseph Postman Plant Pathologist & Curator National Clonal Germplasm Repository Corvallis, Oregon May 2010

  2. 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

  3. U.S. National Plant Germplasm System • 441,000 Accessions • 11,000 Species Germplasm Resources Information Network (GRIN) http://www.ars-grin.gov/npgs/

  4. National Clonal Germplasm Repositories

  5. Scope of NPGS Collections: Davis

  6. Scope of NPGS Collections: Geneva Scope of NPGS Collections: Riverside

  7. Scope of NPGS Collections: Corvallis

  8. NCGR Corvallis – Collection Summary10,500 total plant and seed accessions (5100 field plants, 7200 screenhouse plants)

  9. ex situ clonal collections: Screenhouse Orchard

  10. Repository Objectives

  11. Virus Detection

  12. Virus Elimination Heat treatment Micropropagation

  13. Known Infected Accessions

  14. Plant Distribution 2009 521 requests received 5,800 items shipped

  15. Full Pathogen Testing exceeds genebank capabilities

  16. Priorities for Genebank Testing? • Viruses that impact genebank management • Pollen transmitted (Raspberry bushy dwarf, Blueberry shock) • Accessions that are highly requested • core accessions • cultivars

  17. Should we not distribute virus infected accessions?

  18. 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. • ???
