Claim:
1. A method of producing a hybrid spinach seed comprising crossing a first parent spinach plant with a second parent spinach plant and harvesting the resultant hybrid spinach seed, wherein said first parent spinach plant comprises a R6 gene that confers resistance to a spinach plant to downy mildew races Pfs1, Pfs2, Pfs3, Pfs4, Pfs5, Pfs6, Pfs9, Pfs11, Pfs12, Pfs13 and UA4410 and that requires stacking with another downy mildew resistance gene for the spinach plant to have resistance to downy mildew races Pfs1, Pfs2, Pfs3, Pfs4, Pfs5, Pfs6, Pfs7, Pfs8, Pfs9, Pfs10, Pfs11, Pfs12, Pfs13 and UA4410, wherein the R6 gene is as found in a plant grown from seed deposited with the NCIMB under NCIMB accession number 41857.
