2018 Cucurbit Genetics Cooperative Annual Report

The Cucurbit Genetics Cooperative (CGC) was established in 1977 to develop and advance the genetics of economically important cucurbits. CucCAP Team members have contributed many articles to the Cucurbit Genetics Cooperative throughout the years. Members of the CucCAP Team contributing to CGC report#41 for 2018 include authors Todd Wehner and Jim McCreight along with editors, Amnon Levi and Linda Wessel-Beaver.

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).
