Why Breed Wheat at OSU?
- High yield
- Disease resistance
- Improved end-use quality
- Enhancing virus resistance
- Enhancing septoria resistance
- Developing hard red program
- Abiotic stress tolerance (winter hardiness and low pH soils)
Current Research Projects
The OSU wheat breeding program works specifically on winter wheat. 70% of the program focuses on soft white winter wheat; the other 30% is on hard white and hard red winter wheat.
Small White Winter Wheat - Cultivar Development
- Molecular markers
- RIL development
- Identification of markers for resistance to Stripe rust, C-stripe, Fusarium crown rot, and Septoria
- Identification of markers for end-use quality traits
2 gene imidazolinone resistance
- Di-haploids (wheat x maize)
- ABA enhancing
- BYDV siRNA gene slicing
End-use quality evaluations (soft and hard)
- Gliadin work (Celiac Disease)
- Falling number work
Hard Wheat - Hard White and Hard Red (New Program)
Low protein hard quality
- Genotype x fertilizer response
- Bx7 over-expressing gene
Graduate Student Expectations
Goal: Train students to run a breeding program so that they could step in as a field tech/breeder and be able to do every part of the job, including experimental design, planting, combining, note-taking, pesticide application, etc. Students are given at least two projects: one in the field and one in the greenhouse/lab, and must be able to give public presentations; practice obtained in seminar and at field days.
