Abstract

An inbred maize line, designated NP2222, the plants and seeds of inbred maize line NP2222 and descendants thereof, methods for producing a maize plant produced by crossing the inbred line NP2222 with itself or with another maize plant, and hybrid maize seeds and plants produced by crossing the inbred line NP2222 with another maize line or plant. The invention further relates to methods for producing maize lines derived from inbred maize line NP2222 and from hybrid maize lines developed therefrom, and to maize lines derived by use of those methods.

Claims

1. Seed of maize inbred line designated NP2222 representative seed of said maize inbred line having been deposited under ATCC Accession No:

PTA-3967.

2. A maize plant, or part thereof, produced by growing the seed of claim 1.

3. Pollen of the plant of claim 2.

4. An ovule of the plant of claim 2.

5. A maize plant, or part thereof, having all the physiological and morphological characteristics of the plant according to claim 2.

6. Seed produced by selfing the plant according to claim 2 or 5.

7. A tissue culture of regenerable cells of the maize plant according to claim 2.

8. The tissue culture according to claim 7, wherein the regenerable cells are from a tissue selected from the group consisting of embryos, meristems, pollen, leaves, anthers, roots, root tips, silk, flowers, kernels, ears, cobs, husks and stalks.

9. A maize plant regenerated from the tissue culture of claim 7, wherein the plant has all the morphological and physiological characteristics of a maize plant of the inbred line NP2222, seed of said inbred line having been deposited under ATCC Accession No:

PTA-3967.

10. A method for producing maize seed comprising crossing a first parent maize plant with a second parent maize plant and harvesting the resultant maize seed, wherein said first or second parent maize plant is the inbred maize plant of claim 2.

11. The method according to claim 10, wherein said first parent maize plant is different from said second parent maize plant, wherein said resultant seed is hybrid maize seed.

12. The method according to claim 10, wherein the inbred maize plant is the female parent.

13. The method according to claim 10, wherein the inbred maize plant is the male parent.

14. A method for producing maize seed comprising crossing a first parent maize plant with a second parent maize plant and harvesting the resultant maize seed, wherein said first or second parent maize plant is the inbred maize plant of claim 5.

15. The method according to claim 14, wherein said resultant seed is a hybrid maize seed.

16. The method according to claim 14, wherein the inbred maize plant is the female parent.

17. The method according to claim 14, wherein the inbred maize plant is the male parent.
