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 be developed in coordination with other research areas (see below) and 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.

FY16-17 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 RAs that the CP will address either directly or indirectly via coordination with these other RAs.

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.
Objective 8. Elucidate the epidemiology of colonization and survival of Fusarium graminearum on host tissue, disease development, and toxin accumulation.

IV. FHB Management (MGMT)

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.
