Bacterial fruit blotch (BFB) caused by Acidovoraxcitrulli is a major seed-borne disease that affects watermelon (Citrullus lanatus) seedling and fruit production around the world (5,9). A. citrulli can infect all growth stages of the watermelon plant: seeds, seedlings, foliage, flowers, and fruit(5). The scant research on fruit resistance in favor of foliar resistance has three […]
