The invention further encompasses all parts of inbred corn line FX8609, including culturable cells. Additionally provided herein are methods for introducing transgenes into inbred corn line FX8609, and plants produced according to these methods. ## Claims ### Claim 1 A seed of the maize plant FX8609, a representative seed sample of which has been deposited under ATCC Accession Number PTA-13156. ### Claim 2 (depends on 1) A maize plant FX8609, a representative seed sample according to claim 1 of said FX8609 plant having been deposited under ATCC Accession Number PTA-13156. ### Claim 3 (depends on 2) A plant part of the plant of claim 2. ### Claim 4 (depends on 3) The plant part of claim 3, wherein said part is a pollen grain, a protoplast, a cell, a tassel, an anther or an ovule. ### Claim 5 (depends on 3) A maize seed comprising the plant of claim 3, wherein said plant part is a cell. ### Claim 6 (depends on 2) A process for producing maize seed, said process comprising crossing a plant of maize inbred line FX8609 according to claim 2 with a different maize plant. ### Claim 7 (depends on 6) A maize plant or plant part produced by growing the maize seed of claim 6. ### Claim 8 (depends on 2) An F1 hybrid maize seed comprising a maize plant cell of maize plant FX8609 according to claim 2, a representative seed sample of said plant having been deposited under ATCC Accession Number PTA-13156. ### Claim 9 (depends on 2) A method for producing maize seed comprising growing the plant of claim 2 until seed is produced, and harvesting the seed, wherein the harvested seed is inbred or hybrid or haploid seed. ### Claim 10 (depends on 9) A seed produced by the method of claim 9. ### Claim 11 A process of introducing a heritable trait into maize plant FX8609 comprising: (a) crossing FX8609 plants grown from FX8609 seed, representative seed sample of which has been deposited under ATCC Accession Number PTA-13156, with plants of another maize plant that comprise a desired trait to produce hybrid progeny plants, (b) selecting hybrid progeny plants that have the desired trait to produce selected hybrid progeny plants; (c) crossing the selected progeny plants with the FX8609 plants to produce backcross progeny plants; (d) selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of maize inbred plant FX8609 to produce selected backcross progeny plants; and (e) repeating steps (c) and (d) at least three or more times to produce backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of maize inbred plant FX8609 when grown in the same environmental conditions. ### Claim 12 (depends on 11) A plant produced by the process of claim 11. ### Claim 13 (depends on 11) A maize plant having all the physiological and morphological characteristics of inbred plant FX8609 and the trait of claim 11, wherein the desired trait is selected from the group consisting of waxy starch, male sterility or restoration of male fertility, modified carbohydrate metabolism, modified protein metabolism, modified fatty acid metabolism, altered starch, thermotolerant amylase, herbicide tolerance and/or resistance; insect or nematode tolerance and/or resistance, bacterial disease resistance, fungal disease resistance, and viral disease resistance. ### Claim 14 (depends on 13) The maize plant of claim 13, wherein said trait is conferred by a transgene. ### Claim 15 (depends on 14) The maize plant of claim 14, wherein the transgene confers a trait selected from the group consisting of herbicide tolerance and/or resistance; insect or nematode tolerance and/or resistance; resistance to bacterial, fungal, or viral disease; waxy starch; altered starch, thermotolerant amylase, male sterility or restoration of male fertility, modified carbohydrate metabolism, modified protein metabolism and modified fatty acid metabolism. ### Claim 16 (depends on 2) A method of producing a maize plant derived from the inbred plant FX8609, the method comprising the steps of (a) growing a progeny plant wherein one parent of said progeny plant is the plant of claim 2; (b) crossing the progeny plant with itself or a different plant to produce a seed of a progeny plant of a subsequent generation; (c) growing a progeny plant of a subsequent generation from said seed and crossing the progeny plant of a subsequent generation with itself or a different plant; and (d) repeating step (c) for an additional generation to produce a maize plant derived from the inbred plant FX8609. ### Claim 17 (depends on 2) A method for developing a maize plant in a maize plant breeding program, comprising applying plant breeding techniques comprising recurrent selection, backcrossing, pedigree breeding, marker enhanced selection, haploid/double haploid production, or transformation to the maize plant of claim 2, or its parts, wherein application of said techniques results in development of a maize plant. ### Claim 18 (depends on 10) A method of producing a commodity plant product comprising growing the plant from the seed of claim 10, or a part thereof, and producing said commodity plant product comprising protein concentrate, protein isolate, starch, meal, flour or oil therefrom. ### Claim 19 (depends on 10) A method of producing a treated seed of claim 10 comprising obtaining the seed of FX8609 and treating said seed. ### Claim 20 (depends on 2) A maize seed produced by crossing the plant of claim 2 with a different maize plant.
