Fuente: WIPO "tomato" Cucumber plants exhibiting resistance to cucurbit aphid-borne yellows virus (CAB YV) are provided, together with methods of producing, identifying, or selecting plants or germplasm with a cucurbit aphid-bome yellows virus resistance phenotype. Such methods include producing a cucumber plant exhibiting resistance to CABYV, comprising introgressing genomic regions conferring disease resistance; or selecting a cucumber plant exhibiting resistance to CABYV. Compositions, including polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.
