Developing Double Haploids to Expedite Mapping and Enhance Fusarium Head Blight Resistance in Srww
Project Number: 0500-00053-003-58
Start Date: Jul 01, 2013
End Date: Jun 30, 2015
Provide inbred breeding lines having several diverse FHB resistance genes (exotic and native) to six breeding programs for testing in the Southern Winter Wheat (SWW) region and also provide useful markers for selecting the Catbird resistance that has been one of the most effective sources of FHB resistance in the SWW region.
Approximately 200 DH lines will be developed for each population. Single Nucleotide Polymorphism (SNP) genotyping will done at the USDA-ARS North Dakota genotyping lab using an Illumina Infinium SNP assay. Seed of each DH line will be increased and distributed to cooperators for fall 2013 planting at six locations (AR, GA, LA, MD, NC, and VA).
