Project 1: A combination of backcrossing and three-way crosses will be employed using molecular markers to expedite the selection process. Four-way crosses will also be made to add resistance from both parents. Cooperative evaluation of nurseries including the Southern Uniform Scab, the Uniform Southern Wheat, and the GA state performance trial, and FHB double-haploid lines will be evaluated in the misted, inoculated field nursery at Griffin, GA. Additional phenotypic data on FHB resistance will be collected from both native and exotic resistant sources to help us elucidate the type of resistance. Project 2: Doubled haploids (DH) allow quick introgression of resistance genes and can significantly shorten variety development time. We plan to expand the use of this technique for the whole Southern SRWW region by the coordinated development of at least five breeding populations per year through DH production followed by collaborative genotyping and phenotyping across the region once the DH lines are developed and seed is increased for testing.
