Abstract

According to the invention, there is provided seed and plants of the corn variety designated CV448797. The invention thus relates to the plants, seeds and tissue cultures of the variety CV448797, and to methods for producing a corn plant produced by crossing a corn plant of variety CV448797 with itself or with another corn plant, such as a plant of another variety. The invention further relates to corn seeds and plants produced by crossing plants of variety CV448797 with plants of another variety, such as another inbred line. The invention further relates to the inbred and hybrid genetic complements of plants of variety CV448797.

Claims

1. A plant of corn variety CV448797, wherein a sample of seed of corn variety CV448797 has been deposited under ATCC Accession No. PTA-123823.

2. A plant part of the plant of claim 1.

3. The plant part of claim 2, further defined as pollen, an ovule, or a cell.

8. An F₁ hybrid seed produced by crossing a plant of corn variety CV448797 according to claim 1 with a second, distinct corn plant.

9. The F₁ hybrid seed of claim 8, wherein said plant of corn variety CV448797 comprises a transgene that is inherited by the seed, wherein the transgene was introduced into corn variety CV448797 by backcrossing or genetic transformation.

10. An F₁ hybrid plant grown from the seed of claim 8.

16. A method of producing a progeny corn plant comprising applying plant breeding techniques to the plant of claim 1 or an F₁ hybrid thereof to yield said progeny corn plant.

17. The method of claim 16, wherein the plant breeding techniques comprise backcrossing, marker assisted breeding, pedigree breeding, selfing, outcrossing, haploid production, doubled haploid production, or transformation.

18. The method of claim 16, further defined as comprising:

(a) crossing the plant of claim 1 or an F₁ hybrid thereof with itself or a second plant to produce a seed of a progeny plant of a subsequent generation;

(b) growing a progeny plant of a subsequent generation from said seed and crossing the progeny plant of a subsequent generation with itself or a second plant; and

(c) repeating steps (a) and (b) with sufficient inbreeding until an inbred corn plant is produced.

19. A method of producing a commodity plant product, the method comprising obtaining the plant of claim 10 or a part thereof and producing said commodity plant product therefrom.

20. The method of claim 19, wherein the commodity plant product is grain, starch, seed oil, corn syrup, or protein.

4. A seed of corn variety CV448797, wherein a sample of seed of corn variety CV448797 has been deposited under ATCC Accession No. PTA-123823.

5. The seed of claim 4, further comprising a transgene, wherein the transgene was introduced into corn variety CV448797 by backcrossing or genetic transformation.

6. A composition comprising the seed of claim 4 comprised in plant seed growth media, wherein a sample of seed of corn variety CV448797 has been deposited under ATCC Accession No. PTA-123823.

7. The composition of claim 6, wherein the growth media is soil or a synthetic cultivation medium.

11. A plant of corn variety CV448797 further comprising a single locus conversion, wherein a sample of seed of corn variety CV448797 has been deposited under ATCC Accession No. PTA-123823, and wherein said plant otherwise comprises essentially all of the morphological and physiological characteristics of corn variety CV448797 when grown under the same environmental conditions.

12. The plant of claim 11, wherein the single locus conversion comprises a transgene.

13. A seed that produces the plant of claim 11.

14. The seed of claim 13, wherein the single locus confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect or pest resistance, disease resistance, modified fatty acid metabolism, abiotic stress resistance, altered seed amino acid composition, site-specific genetic recombination, and modified carbohydrate metabolism.

15. The seed of claim 14, wherein the herbicide tolerance trait is tolerance to an herbicide selected from the group consisting of glyphosate, sulfonylurea, imidazolinone, dicamba, glufosinate, phenoxy propionic acid, cyclohexanedione, triazine, benzonitrile, PPO-inhibitor herbicides and bromoxynil.
