With no well-established methods to prevent infection in susceptible plants, host-plant resistance is currently the most effective strategy. Despite knowledge of a moderate, positive correlation in resistance to the two diseases in sunflower, detailed analysis of the genetics, in the same populations, has not been conducted. We present results of genome-wide analysis of resistance to both pathogens in a diversity panel of 218 domesticated sunflower genotypes of worldwide origin. We identified 14 Sclerotinia head rot and 7 Phomopsis stem canker unique QTLs, plus 1 co-located QTL for both traits, and observed extensive patterns of linkage disequilibrium between sites for both traits. Most QTLs contained one credible candidate gene, and gene families were common for the two disease resistance traits. These results suggest there has been strong, simultaneous selection for resistance to these two diseases and that a generalized mechanism for defense against these necrotrophic pathogens exists.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Click <strong><em><a href=\"https:\/\/doi.org\/10.1007\/s00122-020-03694-x\" data-type=\"URL\" data-id=\"https:\/\/doi.org\/10.1007\/s00122-020-03694-x\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a><\/em><\/strong> to view the article. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Authors: Cloe S.
