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 […]

Charleston Gray watermelon sequenced

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 […]
