Years of selection for desirable fruit quality traits in dessert watermelon (Citrullus lanatus) has resulted in a narrow genetic base in modern cultivars. Development of novel genomic and genetic resources offers great potential to expand genetic diversity and improve important traits in watermelon. The CucCAP team has developed a high‐quality genome sequence for the principal […]
Cucumber green mottle mosaic virus (CGMMV) is an emerging virus in the U.S. that has caused serious disease outbreaks to watermelon and several other cucurbit crops around the world. Although CGMMV is seed-borne, the mechanism of its transmission from seed to seedling was not fully understood. With increasing activities of off-shore hybrid seed production and […]
The USDA news service posted an article in May 2019 about teamwork among CucCAP scientists on watermelon genomics. The research team, led by ARS geneticist Amnon Levi at the ARS U.S. Vegetable Laboratory, in Charleston, South Carolina, and Zhangjun Fei at the Boyce Thompson Institute in Ithaca, New York, collaborated with scientists at the Boyce Thompson Institute on the assembly […]
Fusarium wilt race 1, caused by the soil-borne fungus Fusarium oxysporum Schlechtend.: Fr. f. sp. niveum (E.F. Sm.) W.C. Snyder & H.N. Hans (Fon), is a major disease of watermelon (Citrullus lanatus) in the United States and throughout the world. While Fusarium wilt race 1 resistance from chromosome 1 has been incorporated into several watermelon […]
NC State Department of Horticulture Watermelon group and the University of Georgia Department of Horticulture Watermelon Breeding group made presentations at the 83rd Southern Region ASHS Watermelon Research Working Group. Watermelon Variety Trials NC State Extension Specialist Jonathan Schultheis and Research Associate Keith Starke conduct annual variety trials on Melon, Pumpkin, Squash, and Watermelon. The Vegetable […]
Extension Plant Pathologists Lina Quesada from NC State and Chris Smart from Cornell join Extension Specialist Mary Hausbeck for a series of Phytophthora and Downy Mildew Workshops for Vegetable Growers at Michigan State University. Phytophthora blight in vegetables and other cucurbits is complicated by the fact that downy mildew may also be a problem. January 23, […]
On location in Davis, California at Cucurbitaceae 2018, we sit down with United States Department of Agriculture postdoctoral research scientist Sandra Branham to talk about her work, why seed companies are taking such an interest in it, and why having to spit out watermelon seed isn’t for her.

The group determined that bottle gourd rootstocks were effective in imparting resistance to the susceptible watermelon scion and released the two bottle gourd rootstocks that were the most effective in conferring resistance.
