The genetic study conducted in this project has characterized the nature of FHB resistance in a winter wheat line that has high resistance to FHB in the field and lower DON accumulation. Markers linked to FHB resistance were validated and can be used within the winter wheat breeding program. Additional work related to the role of semi-dwarfing genes in relation to FHB resistance will provide direction to bvreeders in relation to which semi-dwarfing genes can be used without negatively impacting FHB resistance, benefiting both spring and winter wheat breeding. Additional funds from this study aided in the purchase of equipment to enhance the efficiency of the FHB nursery.
Objectives
- Identification, mapping and characterization of new sources of resistance;
- Development of an integrated disease management system that uses a multi-pronged approach to FHB management.
Key Findings
- The genetic study conducted in this project has characterized the nature of FHB resistance in a winter wheat line that has high resistance to FHB in the field and lower DON accumulation. Markers linked to FHB resistance were validated and can be used to select for resistance in other genetic materials within the winter wheat breeding program. This will improve the efficiency of FHB breeding.
- The additional work related to the role of the semi-dwarfing genes in relation to FHB resistance will provide direction to breeders in relation to which semi-dwarfing genes can be used without negatively impacting FHB resistance. This has benefits for both spring and winter wheat breeding.
Key Takeaway
- Funding for this project purchased seeding and harvest equipment for the University of Manitoba FHB nursery;
- FHB in a winter wheat line with highe resistance and low DON accumulation was characterized;
- Markers linked to FHB resistance were identified and can be used for selection of resistance in future lines.
