7. An F 1 hybrid lettuce plant, or a plant part thereof, produced by growing said seed of claim 6 .
8. The method of claim 5 , wherein one of said lettuce plants is lettuce cultivar M8405 and the other is transgenic.
9. A method of producing a male sterile lettuce plant, wherein the method comprises introducing a nucleic acid molecule that confers male sterility into the lettuce plant of claim 2 .
10. A male sterile lettuce plant produced by the method of claim 9 , wherein said plant comprises said nucleic acid and otherwise comprises all of the morphological and physiological characteristics of lettuce cultivar M8405.
11. A method of producing an herbicide resistant lettuce plant, wherein said method comprises introducing a gene conferring herbicide resistance into the plant of claim 2 , wherein the herbicide resistance is selected from the group consisting of glyphosate, sulfonylurea, imidazolinone, dicamba, glufosinate, phenoxy proprionic acid, L-phosphinothricin, cyclohexone, cyclohexanedione, triazine, and benzonitrile.
12. An herbicide resistant lettuce plant produced by the method of claim 11 , wherein said plant comprises said gene and otherwise comprises all of the morphological and physiological characteristics of lettuce cultivar M8405.
13. A method of producing a pest or insect resistant lettuce plant, wherein said method comprises introducing a gene conferring pest or insect resistance into the plant of claim 2 .
14. A pest or insect resistant lettuce plant produced by the method of claim 13 , wherein said plant comprises said gene and otherwise comprises all of the morphological and physiological characteristics of lettuce cultivar M8405.
15. The lettuce plant of claim 14 , wherein the gene encodes a Bacillus thuringiensis endotoxin, and wherein said plant comprises said gene and otherwise comprises all of the morphological and physiological characteristics of lettuce cultivar M8405.
16. A method of producing a disease resistant lettuce plant, wherein said method comprises introducing a gene conferring disease resistance into the plant of claim 2 .
17. A disease resistant lettuce plant produced by the method of claim 16 , wherein said plant comprises said gene and otherwise comprises all of the morphological and physiological characteristics of lettuce cultivar M8405.
18. A method of producing a lettuce plant with a value-added trait, wherein said method comprises introducing a gene conferring a value-added trait into the plant of claim 2 , where said gene encodes a protein selected from the group consisting of a ferritin, a nitrate reductase, and a monellin.
19. A lettuce plant with a value-added trait produced by the method of claim 18 , wherein said plant comprises said gene and otherwise comprises all of the morphological and physiological characteristics of lettuce cultivar M8405.
20. A method of introducing a desired trait into lettuce cultivar M8405 wherein the method comprises:
(a) crossing a M8405 plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-124636, with a plant of another lettuce cultivar that comprises a desired trait, 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 and viral disease;
(b) selecting one or more progeny plants that have the desired trait;
(c) backcrossing the selected progeny plants with lettuce cultivar M8405 plants to produce backcross progeny plants;
(d) selecting for backcross progeny plants that have the desired trait; and
(e) repeating steps (c) and (d) two or more times in succession to produce selected third or higher backcross progeny plants that comprise the desired trait.
21. A lettuce plant produced by the method of claim 20 , wherein the plant has the desired trait and otherwise all of the physiological and morphological characteristics of lettuce cultivar M8405.
22. The lettuce plant of claim 21 , wherein the desired trait is herbicide resistance and the resistance is conferred to an herbicide selected from the group consisting of glyphosate, sulfonylurea, imidazolinone, dicamba, glufosinate, phenoxy proprionic acid, L-phosphinothricin, cyclohexone, cyclohexanedione, triazine, and benzonitrile.
