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 […]

Watermelon rootstock proves resistant to disease and pests
A new watermelon line, developed by Agricultural Research Service (ARS) and Clemson University scientists, is serving as a solution against major disease and pests of watermelon crops in the southern U.S., says the USDA. The innovative variety is a rootstock watermelon called Carolina Strongback. It is resistant to both Fusarium wilt and the southern root-knot […]
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 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 […]
