Cucurbita plant resistant to potyvirus
First Claim
1. A cultivated Cucurbita pepo plant comprising a recessive genetic determinant which is capable of directing or controlling resistance to potyvirus, wherein said genetic determinant is a genetic determinant of Cucurbita pepo cv. 268NiW, representative seed of which is deposited at NCIMB under accession number NCIMB 41727, and said genetic determinant is:
- a genetic determinant that is genetically linked to marker locus Ni+, which marker locus comprises a single nucleotide polymorphism (SNP) and co-segregates with the potyvirus resistance trait and said marker locus can be identified in the genome of said plant in a PCR by amplification of a DNA fragment containing the marker locus with the pair of oligonucleotide primers;
forward primer of SEQ ID NO;
13 and reverse primer of SEQ ID NO;
14 followed by detection of the marker locus with resistant allele specific probe SEQ ID NO;
15, wherein the marker comprises a nucleotide C corresponding to position 13 of SEQ ID NO;
15.

Abstract
The present invention relates to a Cucurbita plant, in particular a squash plant, having wide spectrum resistance to potyvirus such as Zucchini Yellow Mosaic Virus (ZYMV), Watermelon Mosaic Virus (WMV), Papaya Ringspot Virus (PRSV) and Moroccan watermelon mosaic virus (MWMV). Methods of selecting a squash plant having wide spectrum potyvirus resistance by marker assisted breeding are also provided.
