Phenotypic data has been gathered on 260 lines in an association mapping population for the diseases of Sclerotinia head rot, Sclerotinia stalk rot, and Phomopsis stalk rot in inoculated, multi-location field trials over the last several years. At the same time, a public-private initiative to develop SNP markers has resulted in 8700 markers which can be used for dense coverage in association mapping experiments. All 260 lines were genotyped during the marker discovery work. Sunflower data will be mined using in silico techniques to determine the location of Phomopsis and Sclerotinia resistance QTL, and compared to known QTL and candidate genes for resistance to Sclerotinia.
