Project Description:
Minimizing the impact of Fusarium head blight (FHB) on barley production in the U. S. requires a multi-dimensional, yet focused and coordinated research effort. The Barley Coordinated Project (CP) seeks to combine existing lines of productive research with new avenues of investigation to develop a set of tools and disease management strategies that will minimize disease risk to producers and end-users of barley (Figure 1). This toolbox will consist of: 1) varieties with enhanced levels of resistance to FHB, lower levels of deoxynivalenol (DON), superior agronomic performance, and good end-use quality; 2) chemical formulations, application procedures, and a disease forecasting model, that maximize fungicide efficacy; 3) residue management strategies that reduce the potential of pathogen inoculum to contribute to disease epidemics; and 4) a set of best management practices that incorporate our current understanding of the tools available to combat this disease.
FY10 Research Objectives:
The Barley CP is organized around four of the Research Areas (RA) outlined in the USWBSI Action Plan. A set of 10 objectives are established within these four RA.
I. Variety Development and Host Resistance (VDHR).
| Objective 1. | Screen available Hordeum germplasm for novel sources of resistance. |
| Objective 2. | Map novel QTL for resistance to FHB in barley. |
| Objective 3. | Validate and fine map FHB resistance QTL. |
| Objective 4. | Develop new barley varieties with enhanced resistance to FHB and lower DON. |
II. Gene Discovery and Engineering Resistance (GDER)
| Objective 5. | Identify barley genes differentially regulated in the barley-Fusarium interaction. |
| Objective 6. | Evaluate promising transgenes in adapted genetic backgrounds in regional nurseries. |
III. Pathogen Biology and Genetics (PBG)
| Objective 7. | Investigate host genotype x pathogen interaction for infection, spread, disease development, and accumulation of DON. |
IV. FHB Management (MGMT)
| Objective 8. | Elucidate the epidemiology of colonization and survival of Fusarium graminearum on host tissue, disease development, and toxin accumulation. |
| Objective 9. | Develop and evaluate chemical/biological management strategies that reduce FHB and/or DON in barley. |
| Objective 10. | Develop and promote best management strategies through integrated disease management. |
