Despite decades of research, no watermelon germplasm has been found with immunity, and only a few sources with various levels of resistance have been identified. The genetic basis of resistance was not known and is complicated by low heritability and strong environmental influence. CucCAP researchers identified a BFB resistant citron melon (Citrullus amarus) and used it for QTL mapping. Six QTL were identified, each explain between 5 and 15% of the variation in resistance. This study represents the first identification of QTL associated with resistance to A. citrulli in any cucurbit.<\/p>\n<p>An abstract for <strong><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30739153\" target=\"_blank\" rel=\"noopener noreferrer\">QTL mapping of resistance to bacterial fruit blotch in Citrullus amarus<\/a>\u00a0<\/strong>was first published online in February 2019.
