The National Watermelon Association remains committed to fostering practical, impactful research that addresses the evolving challenges and opportunities facing watermelon growers, shippers, and the broader supply chain. This year’s RFP continues to prioritize applied research with a direct benefit to watermelon production, handling, and food safety. In particular, the NWA welcomes proposals in areas such […]
Cucurbit Genetics Cooperative report #48 | call for papers
Reports should be sent via email to Amnon Levi at the USDA,ARS Vegetable Laboratory by March 15th, 2025.
CucCAP scientist and colleagues review genetics of resistance to major diseases in squash and pumpkin
Many sources of resistance to diseases such as powdery mildew, downy mildew, Phytophthora rot, and aphid and whitefly transmitted viruses have been identified in related Cucurbita species. Geoffrey Meru and colleagues at University of Florida review the use of genomic tools to identify genetic loci conferring resistance to facilitate more efficient deployment of these materials for breeding.
CucCAP scientists collaborate to develop diagnostic guide for fusarium rot of pumpkin and winter squash
Fusarium rot is an important soil-borne disease impacting production and storage of pumpkins and winter squash. A new guide has been published to facilitate diagnosis of this disease by outlining taxonomy, symptoms, isolation, and epidemiology of the disease, and providing morphologic and PCR-based methods to identify the pathogen.
CucCAP scientists study basis for resistance to squash vein yellowing virus resistance in watermelon
Watermelon production in the southeastern U.S. is subject to severe crop losses due to several viruses, including squash vein yellowing virus (SqVYV). Gene expression analysis of a resistant breeding line by the Kousik group at the U.S. Vegetable Laboratory Charleston SC, indicated potential involvement of a variety of defensive responses. These findings can assist further functional studies and the development of SqVYV-resistant watermelon cultivars.
