Resistance to cucurbit yellowing stunting disorder virus (CYSDV) in Cucumis melo L.
HortScience 35 (1), 110-113
Abstract: Forty-four accessions of Cucumis melo L. and related wild species were tested for reaction to a yellowing disease, incited by the recently identified cucurbit yellowing stunting disorder virus (CYSDV), under natural and controlled-inoculation conditions. The C. melo TGR-1551 accession and one Cucumis metuliferus Naud. accession were asymptomatic. The segregation ratios obtained following controlled inoculations of the family produced by crossing TGR-1551 with the susceptible Spanish cv. Piel de Sapo revealed that the resistance to CYSDV in TGR-1551 is conditioned by a dominant allele at one locus. The name Cucurbit yellow stunting and symbol Cys is proposed for this locus.
