Watermelon Team | 2019 CucCAP Progress Report

Watermelon Team members: Amnon Levi (USDA, ARS), Shaker Kousik (USDA, ARS), Kai-shu Ling (USDA, ARS), Cecilia McGregor (Univ. Georgia), Pat Wechter (USDA, ARS), Todd Wehner (North Carolina St. Univ.)
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: Gummy stem blight, Fusarium wilt, Powdery mildew, Phytophthora fruit rot, Papaya ringspot virus (PRSV) and Cucumber green motile mosaic virus (CGMMV).

CucCAP research identifies a cucumber gene for resistances to downy mildew, angular leaf spot and anthracnose

Development of varieties with multiple disease resistances is always an important goal for plant breeders. Dr. Yiqun Weng’s Lab at the Vegetable Crops Research Unit in USDA-ARS, Madison, Wisconsin identified the STAYGREEN gene that is responsible for the PI 197087-derived triple-disease resistances.
