Lastly, breeding for resistance is the most effective method of control against MNSV. Two cultivars in melon that exhibit resistance are “Gulfstream” and the Korean accession PI 161375. Both exhibit a single recessive gene, nsv, which is reported to control the only resistance found to MNSV in melon. [12]
