Fusarium head blight (FHB) caused by the fungus Fusarium graminearum Schwabe [telomorph: Gibberella zeae (Schwein.) Petch.] has been seriously attacking durum wheat (Triticum turgidum L. var. durum) in North Dakota and the surrounding states. There is continuous decline in harvested durum acreage and production in the durum producing area in the United States because of FHB. Fungicides may reduce the disease but the most environmentally safe and economical way to control the disease is with genetic resistance. The Durum Coordinated Project (CP) has been created under the direction of the USWBSI to accomplish the initiative action plans. The CP’s main objective is to develop FHB resistant durum wheat germplasm (lines/cultivars) with low DON levels, good agronomic traits, and good quality traits that will serve the producers, the domestic pasta industry, and the international export market. Reducing the impact of FHB requires a multidisciplinary effort and therefore the CP includes plant breeders, pathologists, geneticists, and researchers working in the area of disease management. The CP also includes stakeholders such as millers and pasta manufactures.
FY12-13 Research Ojectives:
- Search for novel sources of resistance to FHB in durum and its tetraploid relatives.
- Identify, map, and validate FHB resistance QTL in the newly identified sources of resistance and develop user-friendly molecular markers to assist selection in durum breeding and germplasm development.
- Incorporate FHB resistance QTL from tetraploid and hexaploid wheat accessions into adapted durum backgrounds and develop elite durum germplasm with the assistance of molecular markers in selection.
- Develop durum varieties with enhanced level of FHB resistance and reduced DON accumulation.
- Investigate host genotype x pathogen chemotype/genotype interaction for FHB and DON.
- Evaluate chemical management strategies that reduce FHB and/or DON in durum.
- Develop and promote best management strategies through integrated disease management.
