Abstract

An inbred maize line, designated NP2276, the plants and seeds of inbred maize line NP2276 and descendants thereof, methods for producing a maize plant produced by crossing the inbred line NP2276 with itself or with another maize plant, and hybrid maize seeds and plants produced by crossing the inbred line NP2276 with another maize line or plant. The invention further relates to methods for producing maize lines derived from inbred maize line NP2276 and from hybrid maize lines developed therefrom, and to the maize lines derived by use of those methods.

Claims

1. Seed of maize inbred line designated NP2276 representative seed of said maize inbred line having been deposited under ATCC Accession No:

PTA-4002.

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

6. A maize plant or part thereof produced from the maize plant according to claim 2 or 5, by transformation with a transgene that confers upon said maize plant or part thereof tolerance to a herbicide.

7. A maize plant according to claim 6, wherein said herbicide is glyphosate, gluphosinate, a sulfonylurea herbicide an imidazolinone herbicide, a hydroxyphenylpyruvate dioxygenase inhibitor or a protoporphyrinogen oxidase inhibitor.

8. A maize plant or a part thereof produced from the maize plant according to claim 2 or 5, by transformation with an expression vector comprising a transgene that confers upon said maize plant or a part thereof insect resistance, disease resistance or virus resistance.

9. The maize plant according to claim 8, wherein said transgene is a Bacillus thuringiensis Cry1Ab gene.

10. The maize plant according to claim 9, wherein said expression vector further comprises a bar gene.

11. Seed produced by selfing the plant according to claim 2 or 5, wherein said seed produce plants having all the physiological and morphological characteristics of inbred line NP NP2276, seed of said inbred line having been deposited under ATCC Accession No:

PTA-4002.

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

13. The tissue culture according to claim 12, wherein the regenerable cells are from a tissue selected from the group consisting of embryo, meristem, pollen, leaf, anther, root, root tip, silk, flower, kernel, ear, cob, husk and stalk.

14. A maize plant regenerated from the tissue culture of claim 12, having the morphological and physiological characteristics of inbred line NP2276, seed of said inbred line having been deposited under ATCC Accession No:

PTA-4002.

15. 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 or 5.

16. The method according to claim 15, wherein said first parent maize plant is different from said second parent maize plant, wherein said resultant seed is a hybrid maize seed.

17. The method according to claim 15, wherein the inbred maize plant is the female parent.

18. The method according to claim 15, wherein the inbred maize plant is the male parent.

19. A method of introducing a desired trait into maize inbred line NP2276 comprising:

a) crossing NP2276 plants grown from seed deposited under ATCC Accession No. PTA-4002, with plants of another maize line that comprise a desired trait to produce F1 progeny plants, wherein the desired trait is selected from male sterility, herbicide resistance, insect resistance, and resistance to bacterial, fungal or viral disease;

(b) selecting F1 progeny plants that have the desired trait to produce selected F1 progeny plants;

(c) crossing the selected progeny plants with NP2276 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 line NP2276 to produce selected backcross progeny plants; and

(e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of maize inbred line NP2276 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.

20. A plant produced by the method of claim 19, wherein the plant has the desired trait and all of the physiological and morphological characteristics of corn inbred line NP2276 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.
