Dr. Todd C. Wehner is William Neal Reynolds Distinguished Professor and leader of the cucumber and watermelon breeding project at North Carolina State University.
CucCAP Project
Contributions to the CucCAP project by the Bioinformatics Team, Cucurbit Crop Breeding Teams, and the Integrated Disease Management Team.
Harnessing Genomics for Disease Resistance in Cucumbers, Melons and Squashes | Scientia
Through genomic studies collaborators in the CucCAP project aim to bring disease-resistant cucumbers, melons, squash and watermelon to farmers and hence ensure greater food sustainability into the future.
CucCAP research provides new understanding about transmission of Cucumber green mottle mosaic virus
A recent study determined that CGMMV is seed-borne, but not seed transmitted through seed germination, and evaluated effectiveness of several detection methods.
CucCAP Team 2019 Annual Meeting and Report
CucCAP Project Objectives: Each objective includes integrated research and outreach through extension approaches.
Genomics and Bioinformatics Team | 2019 CucCAP Progress Report
Report from Team members: Zhangjun Fei (Boyce Thompson Institute), Umesh Reddy (West Virginia St. Univ), Amnon Levi (USDA, ARS), Yiqun Weng (USDA, ARS), Michael Mazourek (Cornell University), Pat Wechter (USDA, ARS), Rebecca Grumet (Michigan State University) on Developing genomic and bioinformatic platforms for cucurbit crops and Performing GBS analysis of PI collections, establish core populations of the four species, and provide community resource for genome wide association studies (GWAS).
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).
Melon Team | 2019 CucCAP Progress Report
