Cucurbit yellow stunting disorder virus (CYSDV) is a devastating viral disease of cucurbit crops that has all but eliminated fall season melon production in regions of California and Arizona. Resistance to CYSDV is exhibited by melon PI 313970, a vegetable type melon introduced from India. QTL analysis identified a locus on chromosome 5 that explained 16% – 35% of the variation in virus titer. Markers flanking the QTL were developed for use marker-assisted breeding of CYSDV-resistant melons.
