As a result of many years of domestication, modern watermelon varieties have overall a small root system and are highly susceptible to a wide range of soil-borne diseases. In a recent study, CucCAP researchers in Charleston, SC (USDA, ARS, U.S. Vegetable Laboratory) used a digital imaging technology to evaluate the root systems in 335 watermelon […]

CucCAP scientists uncover QTL associated with sulfur tolerance in melon, facilitating disease control options
CucCAP researchers identified a major QTL associated with sulfur tolerance in a melon mapping population. Genetic markers were developed for the major QTL and can be used to incorporate sulfur tolerance in melon breeding programs.
Watermelon Team | 2020 CucCAP Progress Report
Overall objectives: Identifying quantitative trait loci (QTL) associated with resistance to major and emerging diseases, developing useful molecular markers and utilizing the genomic tools to incorporate resistance into watermelon cultivars. Major diseases: Fusarium wilt, Gummy stem blight, Powdery mildew, Phytophthora fruit rot, Papaya ringspot virus (PRSV) and Cucumber green motile mosaic virus (CGMMV). Team Members: […]

Managing Fusarium Wilt Disease in Watermelons | VSCNews
Vegetable & Specialty Crop News reports on crop and disease management information from UGA: Watermelon plants can become infected in multiple ways. The pathogen can produce spores that survive in the soil, be seedborne and be introduced to fields where watermelons have never been grown. View UGA Cooperative Extension Bulletin 1485 • Fusarium Wilt of […]

CucCAP Researchers Map New Source of Resistance to Bacterial Fruit Blotch in Watermelon
Bacterial fruit blotch (BFB) of cucurbits caused by Acidovorax citrulli has the potential to devastate production of watermelon and other cucurbits. 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.
