| Claim: | We claim |
| Claim: | 1. Hybrid maize seed designated 3476, representative seed of said hybrid 3476 having been deposited under ATCC accession number 203831. |
| Claim: | 2. A maize plant, or its parts, produced by the seed of claim 1. |
| Claim: | 3. Pollen of the plant of claim 2. |
| Claim: | 4. An ovule of the plant of claim 2. |
| Claim: | 5. A tissue culture of regenerable cells of a hybrid maize plant 3476, representative seed of said hybrid maize plant 3476 having been deposited under ATCC accession number 203831, wherein the tissue regenerates plants, said plants capable of expressing all the morphological and physiological characteristics of said hybrid maize plant 3476. |
| Claim: | 6. A tissue culture according to claim 5, the cells or protoplasts being from a tissue selected from the group consisting of leaves, pollen, embryos, roots, root tips, anthers, silks, flowers, kernels, ears, cobs, husks, and stalks. |
| Claim: | 7. A maize plant, or its parts, regenerated from the tissue culture of claim 5 and capable of expressing all the morphological and physiological characteristics of hybrid maize plant 3476, representative seed having been deposited under ATCC accession number 203831. |
