Lettuce cultivar green thunder
View Patent ↗A novel romaine lettuce cultivar, designated Green Thunder, is disclosed. The invention relates to the seeds of lettuce cultivar Green Thunder, to the plants of lettuce cultivar Green Thunder and to methods for producing a lettuce plant by crossing the cultivar Green Thunder with itself or another lettuce cultivar. 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 cultivars derived from the cultivar Green Thunder.
1. A seed of lettuce cultivar Green Thunder, wherein a representative sample of seed of said cultivar was deposited under ATCC Accession No. PTA-8605.
2. A lettuce plant, or a part thereof, produced by growing the seed of claim 1 .
3. A tissue culture of 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 leaf, pollen, embryo, cotyledon, hypocotyl, meristematic cell, root, root tip, anther, pistil, flower, and stem.
4. A protoplast produced from the plant of claim 2 .
5. A protoplast produced from the tissue culture of claim 3 .
6. A lettuce plant regenerated from the tissue culture of claim 3 , wherein the plant has all the morphological and physiological characteristics of cultivar Green Thunder.
7. A method for producing an F 1 hybrid lettuce seed, wherein the method comprises crossing the plant of claim 2 with a different lettuce plant and harvesting the resultant F 1 hybrid lettuce seed.
8. A hybrid lettuce seed produced by the method of claim 7 .
9. A hybrid lettuce plant, or a part thereof, produced by growing said hybrid seed of claim 8 .
10. A method for producing a male sterile lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a nucleic acid molecule.
11. A male sterile lettuce plant produced by the method of claim 10 .
12. A method for producing an herbicide resistant lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a transgene wherein the transgene confers resistance to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine and benzonitrile.
13. An herbicide resistant lettuce plant produced by the method of claim 12 .
14. 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.
15. An insect resistance lettuce plant produced by the method of claim 14 .
16. The lettuce plant of claim 15 wherein the transgene encodes a Bacillus thuringiensis endotoxin.
17. 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.
18. A disease resistant lettuce plant produced by the method of claim 17 .
19. 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.
20. A lettuce plant with a value-added trait produced by the method of claim 19 .
21. A lettuce plant, or a part thereof, having all the physiological and morphological characteristics of the cultivar Green Thunder, wherein a representative sample of seed of said cultivar was deposited under ATCC Accession No. PTA-8605.
22. A method of introducing a desired trait into lettuce cultivar Green Thunder wherein the method comprises:
a. crossing a Green Thunder plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-8605, with a plant of another lettuce cultivar that comprises a desired trait to produce progeny plants, wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, and resistance to bacterial disease, fungal disease, or viral disease;
b. selecting progeny plants that have the desired trait to produce selected progeny plants;
c. crossing the selected progeny plants with the Green Thunder 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 Green Thunder listed in Table 1; 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 all of the physiological and morphological characteristics of lettuce cultivar Green Thunder listed in Table 1.
23. A plant produced by the method of claim 22 , wherein the plant has the desired trait and all of the physiological and morphological characteristics of lettuce cultivar Green Thunder listed in Table 1.
24. The plant of claim 23 , 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.
25. The plant of claim 23 , wherein the desired trait is insect resistance and the insect resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.
26. The plant of claim 23 , wherein the desired trait is male sterility and the trait is conferred by a nucleic acid molecule.
