Abstract

A maize variety designated X05P336 and seed, plants and plant parts thereof are produced by crossing inbred maize varieties. Methods for producing a maize plant by crossing hybrid maize variety X05P336 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X05P336 through backcrossing or genetic transformation, and to the maize seed, plant and plant part produced thereby are described. Maize variety X05P336, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X05P336 are provided. Methods for producing maize varieties derived from maize variety X05P336 and methods of using maize variety X05P336 are disclosed.

Claims (20)

1. A seed of hybrid maize X05P336 produced by crossing a first plant of maize line PH2DNP with a second plant of maize line PH48B8, wherein representative seeds of the maize lines PH2DNP and PH48B8 have been deposited under ATCC Accession Number PTA-124160 and NCMA Accession Number 202004029, respectively.

2. A plant or plant part of hybrid maize X05P336 grown from the seed of claim 1 , wherein the plant part comprises at least one hybrid maize X05P336 cell.

3. A method of producing the seed of claim 1 , the method comprising crossing a plant of the maize line PH2DNP with a plant of the maize line PH48B8, wherein representative seeds of the maize lines PH2DNP and PH48B8 have been deposited under ATCC Accession Number PTA-124160 and NCMA Accession Number 202004029, respectively.

4. A seed of hybrid maize X05P336 produced by crossing a first plant of maize line PH2DNP with a second plant of maize line PH48B8, wherein representative seeds of the maize lines PH2DNP and PH48B8 have been deposited under ATCC Accession Number PTA-124160 and NCMA Accession Number 202004029, respectively, further comprising a transgene, wherein the transgene is introduced by backcrossing or genetic transformation into maize line PH2DNP, the maize line PH48B8, or both maize lines PH2DNP and PH48B8, and wherein the seed produces a plant having otherwise all the physiological and morphological characteristics of hybrid maize X05P336 when grown under the same environmental conditions.

5. A seed of hybrid maize X05P336 produced by crossing a first plant of maize line PH2DNP with a second plant of maize line PH48B8, representative seeds of the maize lines PH2DNP and PH48B8 having been deposited under ATCC Accession Number PTA-124160 and NCMA Accession Number 202004029, respectively, further comprising fewer than six locus conversions, wherein the first plant, the second plant or both further comprise the fewer than six locus conversions, and wherein the seed produces a plant expressing the traits conferred by the fewer than six locus conversions and comprising otherwise all the physiological and morphological characteristics of hybrid maize X05P336 when grown under the same environmental conditions.

6. The hybrid maize X05P336 seed of claim 5 , wherein the fewer than six locus conversions confers a property selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

7. The hybrid maize X05P336 seed of claim 5 , further comprising a seed treatment on the surface of the seed.

8. A method for producing nucleic acids, the method comprising isolating nucleic acids from the hybrid maize X05P336 seed of claim 5 .

9. A plant or plant part grown from the hybrid maize X05P336 seed of claim 5 , the plant part comprising at least one hybrid maize X05P336 cell further comprising the fewer than six locus conversions.

10. A method of producing a commodity plant product comprising starch, syrup, silage, fat or protein, the method comprising producing the commodity plant product from the plant or plant part of claim 9 .

11. A method for producing a second maize plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 9 to produce the second maize plant.

12. A method for producing the hybrid maize X05P336 seed of claim 4 , the method comprising crossing a first plant of maize line PH2DNP with a second plant of maize line PH48B8, representative seeds of the maize lines PH2DNP and PH48B8 having been deposited under ATCC Accession Number PTA-124160 and NCMA Accession Number 202004029, respectively, wherein at least one of the maize lines PH2DNP and PH48B8 further comprises the transgene.

13. The seed of claim 4 , further comprising a seed treatment on the surface of the seed.

14. The seed of claim 4 , wherein the transgene confers a property selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

15. A method for producing nucleic acids, the method comprising isolating nucleic acids from the seed of claim 4 .

16. A plant or plant part produced by growing the seed of claim 4 , the plant part comprising at least one hybrid maize X05P336 cell further comprising the transgene.

17. A method for producing nucleic acids, the method comprising isolating nucleic acids from the plant or plant part of claim 16 .

18. A method of producing a commodity plant product comprising starch, syrup, silage, fat or protein, the method comprising producing the commodity plant product from the plant or plant part of claim 16 .

19. A method for producing a second maize plant, the method comprising crossing the maize plant or plant part of claim 16 with itself or with a different maize plant.

20. A method for producing nucleic acids, the method comprising isolating nucleic acids from the plant or plant part of claim 9 .
