abstract

  • 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 monogenic resistance, controlled by the Prv2 allele, and reacts to PRSV by systemic necrotic lesions; plants with the Prv1 allele, described in cultivar WMR-29, remain symptomless (Pitra t and Lecoq, 1983). Fusarium oxysporum f. sp. melonis (FUS) exclusively attacks melon, causing …
