摘　　要：Dear Editor, Potyviruses such as Papaya ring-spot virus （PRSV） cause important yield losses in cucurbits. Two distinct resistant alleles were identified in the Cucumis melo germplasm. Accession PI 414723 （Supplemental Table 1） possesses mono- genic resistance, controlled by the Prv2 allele, and reacts to PRSV by systemic necrotic lesions; plants with the PryI allele, described in cultivar WMR-29, remain symptomless （Pitrat and Lecoq, 1983）. Fusarium oxysporum f. sp. melonis （FUS） exclusively attacks melon, causing severe wilt. Monogenic dominant resistance was described against races O, 1, and 2. The Fore-2 gene, controlling resistance to races 0 and 1, was cloned by Joobeur et al. （2004）, and encodes a nucleotide bindina domain （NB）-Ieucine rich repeat （LRR） protein.Dear Editor, Potyviruses such as Papaya ring-spot virus （PRSV） cause important yield losses in cucurbits.
