Bacterial fruit blotch caused by Acidovorax citrulli is a serious disease of watermelon (Citrullus lanatus) in the U.S. Currently, there are no varieties resistant to the disease. In a 3-year study, 1452 accessions and cultivars were tested for resistance to fruit blotch at the immature fruit stage, where resistance is most important for growers.

CucCAP Researchers Map New Source of Resistance to Bacterial Fruit Blotch in Watermelon
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.
