The present invention relates toplants that are resistant against Cucumber Vein Yellowing Virus (CVYV), and to plant parts derived thereof without the occurrence of necrotic symptoms. The invention further relates to methods of producing said plants, to CVYV-resistant plants obtainable by said methods, as well as to plant parts derived from said CVYV-resistant plants. Specifically, the present invention relates to a plant of the species, comprising in its genome a genetic element, said genetic element comprising a Cucumber Vein Yellowing Virus (CVYV)-resistance conferring Quantitative Trait Locus (QTL), or a CVYV-resistance conferring part thereof, genetically linked to at least one molecular marker, wherein said marker is selected from a group consisting of E13/M48-259.69-P2, E16/M48-377.36-P2, E13/M48-261.30-P2 and E26/M62-076.8-P2.

A new hybrid cucumber designated 'Jurassic' is described. 'Jurassic' is an oriental-type slicer cucumber that also has intermediate resistance to cucumber mosaic virus and cucumber vein yellowing virus.

Hybrid cucumber 'jurassic'

A hybrid cucumber designated Macario is disclosed that has moderate resistance to powdery mildew and cucumber mosaic virus, and has resistance to cucumber vein yellowing virus and scab and gummosis. The invention relates to the seeds of hybrid cucumber Macario, to the plants of hybrid cucumber Macario, and to methods for producing a cucumber plant, either inbred or hybrid, by crossing the hybrid Macario with itself or another cucumber plant. The invention further relates to methods for producing a cucumber plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other cucumber lines, cultivars, or hybrids derived from the hybrid cucumber Macario.

A hybrid cucumber designated Menfis is disclosed having resistance to powdery mildew (), cucumber mosaic virus, and cucumber vein yellowing virus. The invention relates to the seeds of hybrid cucumber Menfis, to the plants of hybrid cucumber Menfis, and to methods for producing a cucumber plant, either inbred or hybrid, by crossing the hybrid Menfis with itself or another cucumber plant. The invention further relates to methods for producing a cucumber plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other cucumber lines, cultivars, or hybrids derived from the hybrid cucumber Menfis.

A hybrid cucumber designated 'Corinto' is disclosed having resistance to powdery mildew (), cucumber mosaic virus and cucumber vein yellowing virus. The invention relates to the seeds of hybrid cucumber 'Corinto,' to the plants of hybrid cucumber &#x2018;Corinto&#x2019; and to methods for producing a cucumber plant, either inbred or hybrid, by crossing the hybrid &#x2018;Corinto&#x2019; with itself or another cucumber plant. The invention further relates to methods for producing a cucumber plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other cucumber lines, cultivars or hybrids derived from the hybrid cucumber &#x2018;Corinto.&#x2019;

A hybrid cucumber designated Enki is disclosed having resistance to powdery mildew (), cucumber mosaic virus, and cucumber vein yellowing virus. The invention relates to the seeds of hybrid cucumber Enki, to the plants of hybrid cucumber Enki, and to methods for producing a cucumber plant, either inbred or hybrid, by crossing the hybrid Enki with itself or another cucumber plant. The invention further relates to methods for producing a cucumber plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other cucumber lines, cultivars, or hybrids derived from the hybrid cucumber Enki.

Cucumber hybrid enki

A method for producing aplant, providing cucumber fruits exhibiting 'extended shelf life, comprising: (a) providing a firstplant containing at least one quantitative trait locus (QTL); (b) crossing the first plant with a secondplant; (c) analyzing the progeny for presence or absence of QTL; and (d) identifying and selecting plants containing QTL. The QTL is selected from QTL1 or QTL2. QTL1 has a first molecular marker of SEQ ID No:1, a cucumber genomic fragment, and SEQ ID No:2, and a second molecular marker of SEQ ID No:3, a cucumber genomic fragment, and SEQ ID No:4. QTL2 has a first molecular marker of SEQ ID No:5, a cucumber genomic fragment, and SEQ ID No:6, and a second molecular marker of SEQ ID No:7, a cucumber genomic fragment, and SEQ ID No:8.

Method for providing cucumber fruits with an extended shelf life

A hybrid cucumber cultivar designated 'Paraiso' is disclosed which is the first parthenocarpic slicing cucumber that also has intermediate resistance to powdery mildew, cucumber mosaic virus, cucumber vein yellowing virus and cucumber yellow stunting disorder virus. The invention relates to the seeds of hybrid cucumber cultivar 'Paraiso', to the plants of hybrid cucumber cultivar &#x2018;Paraiso&#x2019; and to methods for producing a cucumber plant, either inbred or hybrid, by crossing the hybrid cultivar &#x2018;Paraiso&#x2019; with itself or another cucumber cultivar. The invention further relates to methods for producing a cucumber plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other cucumber cultivars derived from the hybrid &#x2018;Paraiso&#x2019;.
