CucCAP Researchers Map New Source of Resistance to Bacterial Fruit Blotch in Watermelon

Bacterial fruit blotch (BFB) of cucurbits caused by Acidovorax citrulli has the potential to devastate production of watermelon and other cucurbits. Despite decades of research, no watermelon germplasm has been found with immunity, and only a few sources with various levels of resistance have been identified. The genetic basis of resistance was not known and […]

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.

CucCAP scientists release genome of principal American watermelon cultivar and genetically characterize the National Plant Germplasm System watermelon collection

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 […]

Harnessing Genomics for Disease Resistance in Cucumbers, Melons and Squashes | Scientia

Cucurbits are an important source of food worldwide and are economically important. These crops experience a high level of disease pressures from a suite of common diseases. 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

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 […]

CucCAP research identifies novel genetic source of resistance to Fusarium wilt race 1 in wild watermelon

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 […]

Cuccap Project Develops Extension Fact Sheets for Important Cucurbit Diseases in English and Spanish

Members of the CucCAP extension team [Dr. Mary Hausbeck, Michigan State University; Dr. Angela Linares, University of Puerto Rico at Mayaguez; Dr. Lina Quesada-Ocampo, North Carolina State University; Dr. Chris Smart, Cornell University] have developed 16 extension fact sheets to support stakeholders and impact cucurbit production in each region.  The fact sheets provide useful information […]
