Methods for producing a maize plant that comprises crossing hybrid maize variety X90C502 with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X90C502 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the maize variety X90C502, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X90C502. This invention further relates to methods for producing maize varieties derived from maize variety X90C502. ## Claims ### Claim 1 A hybrid maize variety X90C502 seed, wherein representative seed is produced by crossing a first plant of variety PH13HK with a second plant of variety PHWPD, and wherein representative seed of said varieties PH13HK and PHWPD have been deposited under ATCC Accession Number PTA-13012 and PTA-11978, respectively. ### Claim 2 (depends on 1) The hybrid maize variety X90C502 seed of claim 1, wherein a seed treatment has been applied to the seed. ### Claim 3 (depends on 1) A method of cleaning the hybrid maize variety X90C502 comprising obtaining the seed of claim 1 and removing foreign debris from said seed. ### Claim 4 (depends on 1) A method of plant breeding comprising a) isolating nucleic acids from the hybrid maize variety X90C502 seed of claim 1, b) identifying one or more molecular markers from the isolated nucleic acids to produce a molecular marker profile, and c) selecting a plant having the molecular marker profile wherein the plant is used in a plant breeding method. ### Claim 5 (depends on 1) A plant, plant part, or cell produced by growing the hybrid maize variety X90C502 seed of claim 1. ### Claim 6 (depends on 5) A method of plant breeding comprising a) isolating nucleic acids from the plant, plant part, or cell of claim 5, b) identifying one or more molecular markers from the isolated nucleic acids to produce a molecular marker profile, and c) selecting a plant having the molecular marker profile wherein the plant is used in a plant breeding method. ### Claim 7 (depends on 5) A method of producing a commodity plant product comprising obtaining the plant or plant part of claim 5 and producing said commodity plant product therefrom. ### Claim 8 (depends on 5) A method for producing a second maize plant comprising applying plant breeding techniques to a first maize plant, or parts thereof, wherein said first maize plant is the maize plant of claim 5, and wherein application of said techniques results in the production of said second maize plant. ### Claim 9 (depends on 8) The method of claim 8 further comprising: (a) crossing said first maize plant with itself or another maize plant to produce seed of a subsequent generation; (b) harvesting and planting the seed of the subsequent generation to produce at least one plant of the subsequent generation; and (c) repeating steps (a) and (b) for an additional 2-10 generations to produce a second maize plant. ### Claim 10 (depends on 8) The method of claim 8 further comprising: (a) crossing said first maize plant with an inducer variety to produce haploid seed; and (b) doubling the haploid seed to produce a second maize plant. ### Claim 11 A converted seed of hybrid maize variety X90C502, wherein said converted seed is produced by crossing a first plant of variety PH13HK with a second plant of variety PHWPD; wherein representative seed of said varieties PH13HK and PHWPD have been deposited under ATCC Accession Number PTA-13012 and PTA-11978, respectively; and wherein at least one of said varieties PH13HK and PHWPD further comprises a locus conversion, and wherein said converted seed produces a plant having essentially all of the same phenotypic traits listed in Table 1 as X90C502 when grown under the same environmental conditions. ### Claim 12 (depends on 11) The converted seed of hybrid maize variety X90C502 of claim 11, wherein a seed treatment has been applied to the converted seed of hybrid maize variety X90C502. ### Claim 13 (depends on 11) A method of cleaning the converted seed of hybrid maize variety X90C502 comprising obtaining the converted seed of claim 11 and removing foreign debris from said seed. ### Claim 14 (depends on 11) The converted seed of hybrid maize variety X90C502 of claim 11, wherein the locus conversion confers a trait selected from the group consisting of male sterility, site-specific recombination, abiotic stress tolerance, altered phosphorus, altered antioxidants, altered fatty acids, altered essential amino acids, altered carbohydrates, herbicide tolerance, insect resistance and disease resistance. ### Claim 15 (depends on 11) A method of plant breeding comprising a) isolating nucleic acids from the converted seed of hybrid maize variety X90C502 of claim 11 b) identifying one or more molecular markers from the isolated nucleic acids to produce a molecular marker profile, and c) selecting a plant having the molecular marker profile wherein the plant is used in a plant breeding method. ### Claim 16 (depends on 11) A plant, plant part, or cell produced by growing the converted seed of hybrid maize variety X90C502 of claim 11. ### Claim 17 (depends on 16) A method of plant breeding comprising a) isolating nucleic acids from the plant, plant part, or cell of claim 16, b) identifying one or more molecular markers from the isolated nucleic acids to produce a molecular marker profile, and c) selecting a plant having the molecular marker profile wherein the plant is used in a plant breeding method. ### Claim 18 (depends on 16) A method of producing a commodity plant product comprising obtaining the plant or plant part of claim 16 and producing said commodity plant product therefrom. ### Claim 19 (depends on 16) A method for producing a second maize plant comprising applying plant breeding techniques to a first maize plant, or parts thereof, wherein said first maize plant is the maize plant of claim 16, and wherein application of said techniques results in the production of said second maize plant. ### Claim 20 (depends on 19) The method for producing a second maize plant of claim 19, further comprising: (a) crossing said first maize plant with itself or another maize plant to produce seed of a subsequent generation; (b) harvesting and planting the seed of the subsequent generation to produce at least one plant of the subsequent generation; and (c) repeating steps (a) and (b) for an additional 2-10 generations to produce a second maize plant. ### Claim 21 (depends on 19) The method for producing a second maize plant of claim 19, further comprising: (a) crossing said first maize plant with an inducer variety to produce haploid seed; and (b) doubling the haploid seed to produce a second maize plant.
