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
Racehorse Oats White hull High test weight Low proportion of thin kernels (<5/64”) White Yellow
Organic Milling Oats Milling quality High groat Beta-glucan concentration
Organic Oat Milling quality High groat Beta-glucan concentration 30% > B-glucan (6. 5 -7%)
Organic Oat Milling quality High groat Beta-glucan concentration 30% > B-glucan (6. 5 -7%) 30% > health benefits Health benefits/calorie
Groat Beta-glucan Concentration Lines with 20% > BG than Hi. Fi > 9% groat B-glucan Good agronomic performance > health benefits Fewer calories?

Forage Oats Variation among cultivars forage yield Variation among cultivars for quality components related to relative forage value Factors influencing forage value Genotype (lignin concentration) Naked N Dw-6
Factors Influencing Relative Forage Value Naked oats N Dwarf Dw-6 N Dw-6
Factors Influencing Forage Yield and Quality Forage yield and quality may require a tall naked dwarf Dw-6 Tall N Dw-6

Crown Rust Resistance Sources of resistance Amagalon (Hi. Fi, Souris) IA B 605 X (Morton) Avena sterilis derivatives (4 sources) Evaluation of resistance Composite of isolates from the field
Part of the Challenge
Crown Rust Composite Collection of any new virulence observed in the field Recent Virulence Additions Pc-68 Morton (IA B 605 X) Greenhouse seedling evaluation Natural infection in the field
Partial Crown Rust Resistance Bruce Winter, Leslie Research Centre, Toowoomba, Queensland ‘Valley’ (Graza 50) / ‘Jud’ ‘QA 2’ with high level of partial crown rust resistance
Stem Rust Resistance Sources of resistance Pg-13 pg-a complex Amagalon NA 67 Res. Cultivars ‘Jud’ ‘Paul’, ‘Stark’ ‘Maida’
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
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.
