Lettuce cultivar Del Sol
View Patent ↗A novel romaine lettuce cultivar, designated Del Sol, is disclosed. The invention relates to the seeds of lettuce cultivar Del Sol, to the plants of lettuce cultivar Del Sol and to methods for producing a lettuce plant by crossing the cultivar Del Sol 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 Del Sol.
1. A seed of lettuce cultivar Del Sol, representative sample seed of said cultivar was deposited under ATCC Accession No. PTA-9494.
2. A lettuce plant, or a part thereof, produced by growing the seed of claim 1 .
3. A tissue culture produced from protoplasts or cells from the plant of claim 2 , wherein said cells or protoplasts 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, pistil, anther, flower, shoot, stem, seed, and petiole.
4. A lettuce plant regenerated from the tissue culture of claim 3 , wherein the plant has all of the morphological and physiological characteristics of cultivar Del Sol.
5. A method for producing a lettuce seed comprising crossing two lettuce plants and harvesting the resultant lettuce seed, wherein at least one lettuce plant is the lettuce plant of claim 2 .
6. A lettuce seed produced by the method of claim 5 .
7. A lettuce plant, or a part thereof, produced by growing said seed of claim 6 .
8. A method of producing a male sterile lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a nucleic acid molecule that confers male sterility.
9. A male sterile lettuce plant produced by the method of claim 8 .
10. A method of 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.
11. An herbicide resistant lettuce plant produced by the method of claim 10 .
12. A method of producing a pest or insect resistant lettuce plant wherein the method comprises transforming the lettuce plant of claim 2 with a transgene that confers pest or insect resistance.
13. A pest or insect resistant lettuce plant produced by the method of claim 12 .
14. The lettuce plant of claim 13 , wherein the transgene encodes a Bacillus thuringiensis endotoxin.
15. 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.
16. A disease resistant lettuce plant produced by the method of claim 15 .
17. 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.
18. A lettuce plant with a value-added trait produced by the method of claim 17 .
19. A method of introducing a desired trait into lettuce cultivar Del Sol wherein the method comprises:
(a) crossing a Del Sol plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-9494, 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 or pest resistance, modified bolting and resistance to bacterial disease, fungal disease or viral disease;
(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 Del Sol plants to produce backcross progeny plants;
(d) selecting for backcross progeny plants that have the desired trait and all of the physiological and morphological characteristics of lettuce cultivar Del Sol 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 Del Sol listed in Table 1.
20. A lettuce plant produced by the method of claim 19 , wherein the plant has the desired trait.
21. The lettuce plant of claim 20 , 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.
22. The lettuce plant of claim 20 , wherein the desired trait is insect or pest resistance and the insect or pest resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.
