Project 1: We will evaluate the FHB resistance of breeding lines in six cooperative nurseries and the Illinois Wheat Variety Trial. We will evaluate all University of Illinois breeding lines in the misted, inoculated FHB field nursery at Urbana, IL. Approximately 4000 rows will be evaluated in the replicated FHB nursery. Grain spawn (corn kernels cultured with 6-10 FHB isolates) will be used to inoculate the nursery which will be mist-irrigated during flowering. Data will be collected on incidence, severity and percent FDK, FHB and ISK indexes will be calculated and samples will be sent for DON evaluation. Data and germplasm will be shared with other breeding programs within the subregion and across the region. Project 2: Will use the seed produced and selected in the previous year, inoculate with FHB spores at flowering and begin to derive lines by selecting individual FHB resistant plants. Project 3: 1) Phenotype advanced breeding lines that are candidates for release: 2) place FHB and other agronomic, disease resistance, and quality data in database: 3) report on purification and seed increase of the best lines.
