Abstract

A novel maize variety designated PH1K8C and seed, plants and plant parts thereof. Methods for producing a maize plant that comprise crossing maize variety PH1K8C with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PH1K8C through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. Hybrid maize seed, plant or plant part produced by crossing the variety PH1K8C or a locus conversion of PH1K8C with another maize variety.

Claims

1. A seed, plant, plant part, or cell of inbred maize variety PH1K8C, representative seed of said variety having been deposited under ATCC accession number PTA-120726.

2. A method of plant breeding comprising a) isolating nucleic acids from the seed, plant, plant part, or cell of claim 1, b) identifying one or more polymorphisms from the isolated nucleic acids, and c) selecting a plant having one or more of the identified polymorphisms wherein the plant is used in a plant breeding method.

3. A maize seed produced by crossing the plant or plant part of claim 1 with a different maize plant.

4. A maize plant produced by growing the maize seed of claim 3.

5. A method for producing a second maize plant comprising applying plant breeding techniques to a first maize plant, or parts thereof, wherein said first maize plant is the maize plant of claim 4, and wherein application of said techniques results in the production of said second maize plant.

6. The method for producing a second maize plant of claim 5, further comprising:

(a) crossing said first maize plant with itself or another maize plant to produce seed of a subsequent generation;

(b) harvesting and planting the seed of the subsequent generation to produce at least one plant of the subsequent generation; and

(c) repeating steps (a) and (b) for an additional 2-10 generations to produce second maize plant.

7. The second maize plant produced by the method of claim 6, wherein said second maize plant has essentially the same morphological and physiological characteristics of inbred maize variety PH1K8C when grown under the same environmental conditions.

8. The method for producing a second maize plant of claim 5, further comprising:

(a) crossing said first maize plant with an inducer variety to produce haploid seed; and

(b) doubling the haploid seed to produce a second maize plant.

9. The second maize plant produced by the method of claim 8, wherein said second maize plant has essentially the same morphological and physiological characteristics of inbred maize variety PH1K8C when grown under the same environmental conditions.

10. A converted seed, plant, plant part, or cell of inbred maize variety PH1K8C, representative seed of said variety having been deposited under ATCC accession number PTA-120726, wherein said seed, plant, plant part, or cell of inbred maize variety PH1K8C further comprises a locus conversion, and wherein said converted plant or a plant grown from said converted seed comprises essentially all of the physiological and morphological characteristics of inbred maize variety PH1K8C listed in Table 1 when grown in the same environmental conditions.

11. The seed, plant, plant part, or cell of claim 10, wherein the locus conversion confers a trait selected from the group consisting of male sterility, site-specific recombination, abiotic stress tolerance, altered phosphorus, altered antioxidants, altered fatty acids, altered essential amino acids, altered carbohydrates, herbicide tolerance, insect resistance and disease resistance.

12. A method of plant breeding comprising a) isolating nucleic acids from the seed, plant, plant part, or cell of claim 10, b) identifying one or more polymorphisms from the isolated nucleic acids, and c) selecting a plant having one or more of the identified polymorphisms wherein the plant is used in a plant breeding method.

13. A maize seed produced by crossing the plant or plant part of claim 10 with a different maize plant.

14. A maize plant produced by growing the seed of claim 13.

15. A method for producing a second maize plant comprising applying plant breeding techniques to a first maize plant, or parts thereof, wherein said first maize plant is the maize plant of claim 14, and wherein application of said techniques results in production of said second maize plant.

16. The method for producing a second maize plant of claim 15, further comprising:

(a) crossing said first maize plant with itself or another maize plant to produce seed of a subsequent generation;

(b) harvesting and planting the seed of the subsequent generation to produce at least one plant of the subsequent generation; and

(c) repeating steps (a) and (b) for an additional 2-10 generations to produce a second maize plant.

17. The second maize plant produced by the method of claim 16, wherein said second maize plant has essentially the same morphological and physiological characteristics of inbred maize variety PH1K8C when grown under the same environmental conditions.

18. The method for producing a second maize plant of claim 15, further comprising:

(a) crossing said first maize plant with an inducer variety to produce haploid seed; and

(b) doubling the haploid seed to produce a second maize plant.

19. The second maize plant produced by the method of claim 18, wherein said second maize plant has essentially the same morphological and physiological characteristics of inbred maize variety PH1K8C when grown under the same environmental conditions.

20. A second maize seed, plant, plant part, or cell produced by crossing a plant or plant part of inbred maize variety PH1K8C, or a locus conversion thereof, with another maize plant, wherein representative seed of said inbred maize variety PH1K8C has been deposited under ATCC accession number PTA-120726 and wherein said second maize seed, plant, plant part, or cell has 92% of the same polymorphisms for molecular markers listed in Table 4 as the plant or plant part of inbred maize variety PH1 K8C.
