  • Patent number: 9681614
    Abstract: The present invention relates to plant of the species Cucumis melo, said plant comprising a genetic element derived from a plant of the species Cucumis melo var. agrestis, which genetic element comprises a closterovirus-resistance-conferring QTL or a closterovirus-resistance-conferring part thereof linked to at least one marker located on the chromosome equivalent to linkage group (LG) 6 of melon accession PI 313970, wherein said plant is not melon accession PI 313970.

  • Patent number: 8895812
    Abstract: The present invention relates to a plant that is resistant to cucumber closterovirus and resistant to cucumber powdery mildew, wherein said plant is a plant of the species Cucumis sativus, said plant comprising, on a single chromosome, at least one chromosomal region that confers closterovirus resistance and at least one chromosomal region that confers powdery mildew resistance, wherein said at least one region that confers closterovirus resistance is linked to at least one marker selected from the group consisting of markers E16/M50-244, E16/M50-188, and E11/M48-251, and wherein said at least one region that confers powdery mildew resistance is linked to at least one marker selected from the group consisting of: the single nucleotide polymorphism marker 39T?G in SEQ ID NO:1, the single nucleotide polymorphism marker 29G?A in SEQ ID NO:2, the single nucleotide polymorphism marker 193C?T in SEQ ID NO:3, the insertion mutation 5?-AATTT-3? at position 221 in SEQ ID NO:4, and markers E16/M50-F-194, E11/M48-F-

  • Patent number: 8759622
    Abstract: A method for producing cucumber plants which are resistant to cucumber closteroviruses. The method comprises the steps of providing a Cucumis sativus plant which contains alleles that confer resistance to the closteroviruses defined by two QTLs, crossing said C. sativus plant with C. sativus culture breeding material, collecting the seeds resulting from said cross, regenerating the seeds into plants, evaluating the plants for resistance to the closteroviruses, and identifying and selecting resistant plants. Further, a resistant cucumber plant produced by the method as well as fruit or seed produced by said plant.

  • Patent number: 8158852
    Abstract: The present invention relates to a method of producing a plant of the Capsicum genus that exhibits resistance to Pepper mild mottle virus (PMMoV) pathotype 1.2.3, comprising providing a recipient plant of the Capsicum genus that is susceptible to PMMoV pathotype 1.2.3 or a part thereof, and introducing into the genome of the recipient plant or a part thereof or a progeny plant thereof a genomic region comprising a truncated L4 resistance allele, wherein the allele comprises genetic information capable of being expressed in the plant or plant part or progeny plant thereby conferring resistance to PMMoV pathotype 1.2.3 to the plant or plant part or progeny plant, and wherein genetic information that confers the SNFD phenotype is absent from the allele at least to such an extent that the SNFD phenotype is not expressed.
