•Breeding work
•End-use development

Goals for variety testing and development:
• High yield; lodging resistance; disease resistance
• Performance in organic and low-input systems
• Winter-hardiness• Milling quality, nutritional value
•Hulled and Hulless•Spring and Winter•Old and modern•Bringing in germplasm from around the world•Researching end-uses including poultry feed (with Wilcox Family Farms), milling (with Grain Millers Inc.) and forage.
Egg production at Wilcox Family Farm, Roy, WA
Local oatmeal at Camas Country Mills, OR
Commercial variety test
- 50 hulled varieties
- Replicated plot trials in 4 locations spanning the region
- In-field and postharvest tests on milling industry parameters
Hulled oat entriesFrom 9 different breeding programmes across North America and overseas

Results from 2014Yield
•Rankings changed at each site.•Only AC Lu, Kaufmann and Stride were in the top 15 at all three locations.•AC Morgan, Summit, UC 125 and Pinnacle were in the top 15 at both NWREC and Kirsop.•High average yield, low CV: Esker, Chaps, Proleaf 234, Stride, AC Lu.•Cayuse was consistently near the bottom at each location.
Results from 2014Lodging
•Lodging was problematic at three out of four locations.•Entries with especially high lodging resistance across sites were 06-5465, NZA 733/01, Spurs, UC 125 and Shootingstar – unfortunately none of the highest yielders!•Horsepower, Summit and Proleaf 234 emerged as high yielders with reasonable lodging resistance.•Entries with low lodging resistance included Kaufmann, Jim and Newburg.•Lincoln, Newburg, Jury, Kaufmann, Pinnacle and Stride can become extremely tall (over 61in) and are probably best avoided in areas with high probability of summer rainfall.
Results from 2014Test WeightRange (plot-level): 28lb/bu - 46lb/buMilling industry minimum standard is 40lb/buData from Bishops, NWREC and Kirsop:

Results from 2014Test Weight
•Entries exceeding milling minimum at all three locations were Robust, Spurs and Tack.•Many varieties exceeded the minimum at two out of three locations.•Some varieties did not reach the minimum at any location, including Shootingstar and Proleaf 234.
Results from 2014Heading dateRange: 161 – 184 days to heading
•There were some really late varieties: L-5, NZA 228/17, Jordan and Shootingstar.•Early varieties did not necessarily yield less. They included Tack and Horsepower.
Results from 2014Grain quality
Results from 2014Milling tests are now underway to determine•Plumps and thins•Kernel content (% hull)•Nutritional value (protein, oil, beta glucan)
Conclusion:•There are always trade-offs. Information about your farm and climate can point to what your biggest risks are and guide variety choice.•With the right choice of variety, Western Washington oats should be able to easily surpass 5,000lb/a and meet milling standards for test weight.
