In the Fall of 2020, members of the cucurbit community were invited to submit manuscripts for CGC report #43. Editors of the Cucurbit Genetics Cooperative extended the deadline for submitting manuscripts for the 2020 report to February 15, 2021. The cucurbit research community is encouraged to continue to share research, manuscripts, reports, descriptions of new techniques, interesting […]

Cucurbit Genetics Cooperative Report 42
CucCAP scientists and other researchers authored reports in the 2019 Cucurbit Genetics Cooperative (CGC) report which was published in September 2020.
CucCAP researchers identify watermelon root traits to improve tolerance to stress and diseases
In a recent study, CucCAP researchers used a digital imaging technology to evaluate the root systems in 335 watermelon accessions.
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: […]

CucCAP researchers identify genetic loci conferring resistance to Fusarium wilt race 2 and Papaya ring-spot virus-watermelon strain (PRSV-W)
Multiple disease screens of the USDA watermelon germplasm collection have highlighted the value of wild type watermelons as a source for enhancing resistance to diseases in modern watermelon cultivars. CucCAP researchers collaborated with Sakata Seed America on generating genetic populations and on conducting genetic analyses to identify genetic loci that confer resistance to Fusarium wilt and papaya ring-spot virus.
