  1. North Dakota State University Oat BreedingProviding a reason to grow oats

  2. Personnel • Technician Robert Baumann • Graduate Students Diego Vilaro Angela Sebelius • Dr. D.C. Doehlert

  3. Financial Support • Pepsico/Quaker Oats • USDA-ARS National Oat Germplsasm Enhancement Program

  4. Milling Oat Quality • Milling yield ‘AC Assiniboia’ ‘CDC Dancer’ ‘AC Goslin’ • Test Weight ‘Hytest’ and other SD lines • Low groat oil concentration ‘Jerry’ (<6% groat lipid) ‘Morton’ (<5% Groat lipid) • Uniform kernel size • Low proportion of thin kernels (<5/64”) • High groat Beta-glucan concentration (7.0%) • Groat protein concentration

  5. Racehorse Oats • White hull • High test weight • Low proportion of thin kernels (<5/64”) White Yellow

  6. Organic Milling Oats • Milling quality • High groat Beta-glucan concentration

  7. Organic Oat Milling • Milling quality • High groat Beta-glucan concentration • 30% > B-glucan (6.5-7%)

  8. Organic Oat Milling • Milling quality • High groat Beta-glucan concentration • 30% > B-glucan (6.5-7%) • 30% > health benefits • Health benefits/calorie

  9. Groat Beta-glucan Concentration • Lines with 20% > BG than HiFi • > 9% groat B-glucan • Good agronomic performance • > health benefits • Fewer calories?

  10. Weed Competition ‘HiFi’ ‘Jerry’

  11. ‘HiFi’

  12. ‘Jerry’

  13. Forage Oats • Variation among cultivars for forage yield • Variation among cultivars for quality components related to relative forage value • Factors influencing forage value Genotype (lignin concentration) Naked N Dw-6

  14. Factors Influencing Relative Forage Value • Naked oats N • Dwarf Dw-6 N Dw-6

  15. Factors Influencing Forage Yield and Quality • Forage yield and quality may require a tall naked dwarf Tall N Dw-6 Dw-6

  16. Tall Naked Dwarf or Short Tall?

  17. Dw-6 AC Ronald Dw-6 N Solid Stem (Peduncle)

  18. LowLignin?

  19. Disease Resistance • Crown Rust • Stem Rust • Barley Yellow Dwarf Virus

  20. Crown Rust Resistance • Sources of resistance Amagalon (HiFi, Souris) IA B605X (Morton) Avena sterilis derivatives (4 sources) • Evaluation of resistance Composite of isolates from the field

  21. Part of the Challenge

  22. Crown Rust Composite • Collection of any new virulence observed in the field • Recent Virulence Additions Pc-68 Morton (IA B605X) • Greenhouse seedling evaluation Natural infection in the field

  23. Partial Crown Rust Resistance • Bruce Winter, Leslie Research Centre, Toowoomba, Queensland • ‘Valley’ (Graza 50) / ‘Jud’ • ‘QA2’ with high level of partial crown rust resistance

  24. Stem Rust Resistance • Sources of resistance Pg-13 pg-a complex Amagalon • NA67 Res. Cultivars ‘Jud’ ‘Paul’, ‘Stark’ ‘Maida’

  25. Stem and Crown rust resistance linkage issues • pg-a stem rust resistance gene is tightly linked with crown rust susceptibility at the locus that confers crown rust resistance in ‘Morton’. • Identification of recombinant crown and stem rust resistant plant • Amagalon crown rust resistance gene is linked in repulsion to Dw-6

  26. Partial stem rust resistance ND germplasm lines evaluated for production in Queensland Four of 120 lines tested for stem rust resistance were rated as having a high level of partial stem rust resistance.

  27. Innovation • Value added traits • New technology

  28. Reasons to grow oats • Profitability for oat producers
