We identified QTLs associated with gummy stem blight resistance in an interspecific F2:3 Citrullus population and developed marker assays for selection of the loci in watermelon.

CucCAP researchers identify genetic loci conferring resistance to Fusarium wilt race 2 and Papaya ring-spot virus-watermelon strain (PRSV-W)
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. CucCAP researchers collaborated with Sakata Seed America on generating genetic populations and on conducting genetic analyses to identify genetic loci that confer resistance to Fusarium wilt and papaya ring-spot virus.
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.
New Release from the Cucurbit Genomics database
SNPS from GBS data of Cucurbita accessions, including C. pepo, C. maxima and C. moschata are made publicly available prior to publication under a data release policy.
CucCAP scientists release genome of principal American watermelon cultivar and genetically characterize the National Plant Germplasm System watermelon collection
The CucCAP team has developed a high‐quality genome sequence for the principal American dessert watermelon cultivar ‘Charleston Gray’ and genotyped 1365 watermelon PI lines maintained at the U.S. National Plant Germplasm System.
