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, ARS, U.S. Vegetable Laboratory, Charleston, SC collaborated with Sakata Seed America on generating genetic populations and on conducting genetic analyses to identify genetic loci that confer resistance to FW and PRSV. The resistance genetic loci identified in this study are highly valuable for the improvement of disease resistance in elite watermelon cultivars.
