1 Malting Barley Development at OSU Scott Fisk Cascadia Grains Conference January 12, 2013

2 The ancestral state World s oldest crop Native to Middle East Ancestral form is winter habit 2- row hulled

3 2-row vs. 6-row 1 gene/30,000 genes

4 Growth Habit Traits Winter Spring - Faculta2ve Low temperature tolerance: LTT Capacity to survive low temperatures while in a vegetative state Vernalization sensitivity: VRN. Requires cold units to transition from a vegetative to a reproductive state Photoperiod sensitivity: PPD. Will not transition from a vegetative to a reproductive state under short days

5 Uses: Feed, food, and malt

6 Most barley grown in the world today is 2-row, spring habit, and for malt

7 Focus on fall-sown barley WHY? Productivity - 20% yield advantage EfRicient use of resources - less or no irrigation Diversity - erosion control/ double crop

8 Facultative growth habit is the best of all worlds Wider adaptation Production Rlexibility Accelerated breeding

9 Facultative varieties: plant any time Late winter/early spring (~ February) seeding of winter, facultative, or spring varieties is an option for some growers Spring breeding nursery (foreground) and winter breeding nursery (background). Hyslop Farm. Lewisburg, OR 2010

10 Malt vs. Feed A rule of thumb is that good malt barley is good feed barley, but not the reverse. Usually malt barley commands a price premium over feed barley, but malt varieties usually yield less.

11 Malt Buyer Variety Protein Skinned/Broken Plumpness Grower Price Yield Agronomics

12 Malting varieties must meet speciric quality criteria for malting and brewing The maltster and brewer will specify which variety(ies) will be contracted

15 All within a six-row framework Industry support for malting barley development: The foundation of the OSU program a practical justirication for fundamental research

16 The way it was 6- row (North America): vs. 2- row (the world)

17 Shifting from 6 row to 2 row Via Doubled Haploid Production

18 Accelerated generation time Barley is self- pollinated Cross (F1) to F5 (yield trial) Worst case = 1 generation: 1 year Better case = greenhouse, southern hemisphere Best case = doubled haploids

19 Past Maja Culmination of 25 years of breeding facultative*/winter 6-row malting barley. Generous $ from AMBA, BARI, GW; OR, ID barley farmers. Periodic Federal grants. Forays into the basic genetics of low temperature tolerance, growth habit, disease resistance, and malting quality. ~ 100+ publications.
