Abstract: The present invention relates to Cucumis melo plants 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 Cucumis melo, 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.

Abstract: A method for producing a Cucumis sativus plant, providing cucumber fruits exhibiting “extended shelf life, comprising: (a) providing a first Cucumis sativus plant containing at least one quantitative trait locus (QTL); (b) crossing the first plant with a second Cucumis sativus plant; (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.

Abstract: Corresponding results were obtained with A method for obtaining a plant, in particular a cultivated lettuce plant (L. sativa), with a lasting resistance to a pathogen, in particular Bremia lactucae, comprising of providing one or more specific DNA markers linked to one or more resistance genes, determining the presence of one or more resistance genes in a plant using these DNA markers, subsequently crossing a first plant comprising one or more resistance genes with a second plant comprising one or more resistance genes, and selecting from the progeny a plant in which one or more resistance genes are present by using the DNA markers. The invention further relates to the plants obtained with this method, seeds and progeny of these plants, as well as progeny thereof.
