Lettuce named gun slinger
A novel lettuce cultivar, designated GUN SLINGER, is disclosed. The invention relates to the seeds of lettuce cultivar GUN SLINGER, to the plants of lettuce line GUN SLINGER and to methods for producing a lettuce plant by crossing the cultivar GUN SLINGER with itself or another lettuce 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 GUN SLINGER.
1. A seed of lettuce cultivar designated GUN SLINGER, wherein a representative sample of seed of said cultivar has been deposited under NCIMB No. 41772.
2. A lettuce plant, or a part thereof, produced by growing the seed of claim 1 .
3. A lettuce plant, or a part thereof, having all the physiological and morphological characteristics of lettuce cultivar GUN SLINGER listed in Table 1.
4. A lettuce plant, or a part thereof, having the physiological and morphological characteristics of lettuce cultivar GUN SLINGER, wherein a representative sample of seed of said cultivar has been deposited under NCIMB No. 41772.
5. A tissue culture of regenerable cells produced from the plant of claim 2 wherein said cells of the tissue culture are produced from a plant part selected from the group consisting of embryos, meristematic cells, leaves, pollen, root, root tips, stems, anther, pistils, axillary buds, flowers and seeds.
6. A lettuce plant regenerated from the tissue culture of claim 5 , said plant having the morphological and physiological characteristics of lettuce cultivar GUN SLINGER, wherein a representative sample of seed has been deposited under NCIMB No. 41772.
7. A method for producing a 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 second parent lettuce plant is the lettuce plant of claim 2 .
8. A hybrid lettuce seed produced by the method of claim 7 .
9. A method for producing an herbicide resistant plant comprising transforming the lettuce plant of claim 2 with a transgene that confers herbicide resistance to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine, and benzonitrile.
10. An herbicide resistant lettuce plant, or a part thereof, produced by the method of claim 9 .
11. A method for producing an insect resistant lettuce plant comprising transforming the lettuce plant of claim 2 with a transgene that confers insect resistance.
12. An insect resistant lettuce plant, or a part thereof, produced by the method of claim 11 .
13. A method for producing a disease resistant lettuce plant comprising transforming the lettuce plant of claim 2 with a transgene that confers disease resistance.
14. A disease resistant lettuce plant, or a part thereof, produced by the method of claim 13 .
15. A method of introducing a desired trait into lettuce cultivar GUN SLINGER comprising:
(a) crossing a lettuce cultivar GUN SLINGER plant grown from lettuce cultivar GUN SLINGER seed, wherein a representative sample of seed has been deposited under NCIMB No. 41772, with another lettuce plant that comprises a desired trait to produce F 1 progeny plants, wherein the desired trait is selected from the group consisting of insect resistance, disease resistance, water stress tolerance, heat tolerance, improved shelf life, delayed senescence, and improved nutritional quality;
(b) selecting one or more progeny plants that have the desired trait to produce selected progeny plants;
(c) crossing the selected progeny plants with the lettuce cultivar GUN SLINGER plants to produce backcross progeny plants;
(d) selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of lettuce cultivar GUN SLINGER listed in Table 1 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 the physiological and morphological characteristics of lettuce cultivar GUN SLINGER listed in Table 1.
16. A lettuce plant produced by the method of claim 15 , wherein the plant has the desired trait and the physiological and morphological characteristics of lettuce cultivar GUN SLINGER listed in Table 1.
17. A method for producing lettuce cultivar GUN SLINGER seed comprising crossing a first parent lettuce plant with a second parent lettuce plant and harvesting the resultant lettuce seed, wherein both said first and second lettuce plants are the lettuce plant of claim 4 .
18. The lettuce plant of claim 16 , wherein the desired trait is herbicide resistance and the resistance is conferred to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine, and benzonitrile.
19. The lettuce plant of claim 16 , wherein the desired trait is insect resistance and the insect resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.
20. The lettuce plant of claim 16 , wherein the desired trait is selected from the group consisting of insect resistance, disease resistance, water stress tolerance, heat tolerance, improved shelf life, delayed senesence, and improved nutritional quality.
21. A lettuce head, produced by growing the seed of claim 1 .
