Abstract

A novel romaine lettuce cultivar, designated Sunbelt, is disclosed. The invention relates to the seeds of lettuce cultivar Sunbelt, to the plants of lettuce line Sunbelt and to methods for producing a lettuce plant by crossing the cultivar Sunbelt with itself or another lettuce (Lactuca sp.) line. The invention further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other lettuce lines derived from the cultivar Sunbelt.

Claims

1. A seed of lettuce variety designated Sunbelt, representative seed having been deposited under ATCC Accession No. PTA-4564.

2. A lettuce 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 tissue culture of regenerable cells produced from the plant of claim 2.

6. The tissue culture according to claim 5, wherein said cells of the tissue culture are produced from a tissue selected from the group consisting of leaves, pollen, embryos, cotyledons, a hypocotyl, meristematic cells, roots, root tips, anthers, flowers, seeds, and stems.

7. A lettuce plant regenerated from the tissue culture of claim 5, wherein the regenerated plant has all of the morphological and physiological characteristics of lettuce cultivar Sunbelt, representative seed of said lettuce cultivar Sunbelt having been deposited under ATCC Accession No. PTA-4564.

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

9. A method of producing an herbicide resistant lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a transgene that confers herbicide resistance.

10. An herbicide resistant lettuce plant produced by the method of claim 9.

11. A method of producing an insect resistant lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a transgene that confers insect resistance.

12. An insect resistant lettuce plant produced by the method of claim 11.

13. A method of producing a disease resistant lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a transgene that confers disease resistance.

14. A disease resistant lettuce plant produced by the method of claim 13.

15. A method of producing a lettuce plant with a value-added trait, wherein the method comprises transforming the lettuce plant of claim 2 with a transgene encoding a protein selected from the group consisting of a ferritin, a nitrate reductase and a monellin.

16. A lettuce plant with a value-added trait produced by the method of claim 15.
