Methods for producing a maize plant that comprises crossing hybrid maize variety X03C209 with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X03C209 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the maize variety X03C209, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X03C209. This invention further relates to methods for producing maize varieties derived from maize variety X03C209. ## Claims ### Claim 1 A hybrid maize variety X03C209 seed, wherein representative seed is produced by crossing a first plant of variety PH17RD with a second plant of variety PH1K93, and wherein representative seed of said varieties PH17RD and PH1K93 have been deposited under ATCC Accession Number PTA-13091 and PTA-120813, respectively. ### Claim 2 (depends on 1) The hybrid maize variety X03C209 seed of claim 1, wherein a seed treatment has been applied to the seed. ### Claim 3 (depends on 1) A method comprising cleaning the hybrid maize variety X03C209 seed of claim 1. ### Claim 4 (depends on 1) Molecular data wherein said data was collected from isolated nucleic acids from the hybrid maize variety X03C209 seed of claim 1. ### Claim 5 (depends on 1) A plant, plant part, or cell produced by growing the hybrid maize variety X03C209 seed claim 1. ### Claim 6 (depends on 5) Molecular data wherein said data was collected from isolated nucleic acids from the plant, plant part, or cell of claim 5. ### 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 X03C209 further comprising a locus conversion, wherein said converted seed is produced by crossing a first plant of variety PH17RD with a second plant of variety PH1K93; wherein representative seed of said varieties PH17RD and PH1K93 have been deposited under ATCC Accession Number PTA-13091 and PTA-120813, respectively; wherein at least one of said varieties PH17RD and PH1K93 further comprises a locus conversion; and wherein a plant grown from said converted seed has essentially all of the morphological and physiological characteristics of hybrid maize variety X03C209 when grown under the same environmental conditions. ### Claim 12 (depends on 11) The hybrid maize variety X03C209 seed further comprising a locus conversion of claim 11, wherein a seed treatment has been applied to the hybrid maize variety X03C209 seed further comprising a locus conversion. ### Claim 13 (depends on 11) A method comprising cleaning the hybrid maize variety X03C209 seed further comprising a locus conversion of claim 11. ### Claim 14 (depends on 11) The hybrid maize variety X03C209 seed further comprising a locus conversion 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) Molecular data wherein said data was collected from isolated nucleic acids from the hybrid maize variety X03C209 seed further comprising a locus conversion of claim 11. ### Claim 16 (depends on 11) A plant, plant part, or cell produced by growing the hybrid maize variety X03C209 seed further comprising a locus conversion of claim 11. ### Claim 17 (depends on 16) Molecular data wherein said data was collected from isolated nucleic acids from the plant, plant part, or cell of claim 16. ### 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.
