  5. A Brief History • First small grains germplasm obtained in 1897 by USDA • explorers • - Maintained for the first half of the 20th Century by USDA • Cereal Investigators (separate for wheat, barley, oat, rice) • - NSGC officially formed in 1948, combining the separate • collections; located at Beltsville, Maryland • Moved to Aberdeen, Idaho in 1988

  6. Acquisition • Distribution • Maintenance • Evaluations

  7. Maintenance • Regenerations based on seed inventory and viability • Locations • Aberdeen, Idaho – spring and winter wheat, barley, oat, rye, • triticale; Greenhouse – wild species • Parlier, California – winter nursery for mixed habit, tender • Stuttgart, Arkansas & Beaumont, TX – rice • Puerto Rico – long-season rice

  8. Viability StatusInventory Status* High Low Critical High (>70%) 9 8 5 Low (20-70%) 7 6 3 Critical (<20%) 4 2 1 *High - >50g for cultivated species, >10g for wild species Low – 15-50g for cultivated species, 4-10g for wild species Critical - <15g for cultivated species, <4g for wild species

  9. Field design

  10. Population sizes • Self vs cross pollinated • Hills – wild – delnet • Noxious weeds • Inspections • Greenhouse • Notes • Harvest • Cleaning • Replacing
