Abstract

This is a large, multidisciplinary project which seeks to identify genes and environmental stimuli that control variation in a major quality determinant of UK wheat: Hagberg Falling Number (HFN), an industry standard measure of starch integrity. Controlled conditions will be developed and used to help identify candidate genes controlling HFN and to map these against genetic markers identified in a broad range of elite UK germplasm. The objective is to generate and validate DNA markers, ideally within the controlling gene, to enable breeders to select against undesirable alleles in conventional crossing programmes. The John Innes Centre will identify and analyse genetic variation for HFN with additional input from breeding companies' field trials, DNA marker analyses, and novel germplasm. An array of varieties and mapping populations representing HFN diversity among modern UK winter wheats will be trialed and analyzed at two sites over three years, which will enable gene discovery via gene mapping. Collaborations on screening methods (with NIAB, HAUAC, UoN) and on resistance/candidate gene alignments (with RRes, UoN, Biogemma) will integrate efforts to supply the industry with intelligent phenotype and genotype selection tools, for breeding new wheat varieties with stable HFN and enhanced grain quality.
