CucCAP researchers identify genetic loci conferring resistance to Fusarium wilt race 2 and Papaya ring-spot virus-watermelon strain (PRSV-W)

Fusarium wilt (FW) and papaya ring-spot virus-watermelon strain (PRSV-W) are important diseases of watermelon, causing serious damage to the crop. 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. The CucCAP team at the USDA, […]

CucCAP scientists co-led the development of an improved ‘97103’ watermelon genome and resequencing of 414 watermelon accessions

Watermelon has been domesticated for more than 4000 years and modern sweet watermelons have been selected to carry large fruits with crisp, non-bitter and sweet flesh. The CucCAP team has co-led an international effort to generate an improved watermelon ‘97103’ reference genome and resequence 414 accessions from the seven extant Citrullus species.

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 […]

Harvesting Genes to Improve Watermelons | The Global Plant Council

Publications from CucCAP scientists Zhangjun Fei and Amnon Levi were highlighted in a recent article from The Global Plant Council. In the past 20 to 30 years, plant breeders have crossed cultivated watermelon with the sister species C. amarus and two other wild relatives, C. mucusospermus and C. colocynthis, to make the dessert watermelon more resistant to nematode pests, drought, […]

Winter 2019 Extension Disease Management Workshops

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, […]

CucCAP team developed a new database for cucurbit genomics

During the past several years, large amounts of genomic, transcriptomic and genetic data have been accumulated for cucurbits. These data have been extensively used to facilitate cucurbit research and breeding. However, efficient access, and ability to mine and analyze these large-scale datasets pose challenges to researchers, especially those with limited bioinformatics expertise. Therefore, the CucCAP […]
