Research Project: Fusarium Head Blight Research in Winter Wheat Project Number: 0500-00053-003-85
Project Type: Grant

Start Date: May 27, 2014
End Date: May 26, 2015

Objective:
Project 1 - Accelerating the Development of Scab resistant Soft Red Winter Wheat: Continue to discover novel sources of FHB resistance in genetic backgrounds adapted to the soft red winter wheat growing areas. Project 2 - Male Sterile Facilitated Recurrent Selection for FHB Resistance (MPI-5): The objective of this project is to advance male-sterile facilitated recurrent selection populations that have been developed to combine genes for FHB resistance from multiple sources in soft winter wheat backgrounds adapted to the eastern U.S. Project 3 - Coordinated Phenotyping of Uniform Nurseries and Official Variety Trials: Screen and Evaluate approx. 450 unique advanced breeding lines and released cultivars for FHB resistance.

Approach:
Project 1: (1) the continued design of crosses that combine FHB-resistant parents with native and/or exotic sources of resistance; (2) systematic screening of advanced breeding lines for all 4 types of FHB resistance and verification of resistance levels in lines with putative resistance identified in previous years of screening; (3) increasing a mapping population for MO 080104 which carries no known markers for FHB with the ultimate goal in FY15 of phenotyping this population in both the field and greenhouse environments; (4) greenhouse and field screening of 300 F7 RILs of a mapping population developed from the cross Bess/MO 94-317 to validate Truman FHB markers as Bess is a full sib of Truman that has FHB resistance. 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.
