The invention thus relates to the plants, seeds and tissue cultures of lettuce line SV6881LG, and to methods for producing a lettuce plant produced by crossing a plant of lettuce line SV6881LG with itself or with another lettuce plant, such as a plant of another line. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of a plant of lettuce line SV6881LG, including the gametes of such plants. ## Claims ### Claim 1 A seed of lettuce line SV6881LG, a sample of seed of said line having been deposited under ATCC Accession Number PTA-121367. ### Claim 2 (depends on 1) A plant grown from the seed of claim 1. ### Claim 3 (depends on 2) A plant part of the plant of claim 2. ### Claim 4 (depends on 3) The plant part of claim 3, wherein said part is selected from the group consisting of a pollen, an ovule and a cell. ### Claim 5 (depends on 2) A lettuce plant, or a part thereof, having all the physiological and morphological characteristics of the lettuce plant of claim 2. ### Claim 6 A tissue culture of regenerable cells of lettuce line SV6881LG, a sample of seed of said line having been deposited under ATCC Accession Number PTA-121367. ### Claim 7 (depends on 6) The tissue culture according to claim 6, comprising cells or protoplasts from a plant part selected from the group consisting of embryos, meristems, cotyledons, pollen, leaves, anthers, roots, root tips, pistil, flower, seed and stalks. ### Claim 8 (depends on 6) A lettuce plant regenerated from the tissue culture of claim 6, wherein the regenerated plant expresses all of the physiological and morphological characteristics of lettuce line SV6881LG, a sample of seed of said line having been deposited under ATCC Accession Number PTA-121367. ### Claim 9 (depends on 2) A method of producing lettuce seed, comprising crossing the plant of claim 2 with a second lettuce plant. ### Claim 10 (depends on 9) The method of claim 9, wherein the plant of lettuce line SV6881LG is the female parent. ### Claim 11 (depends on 9) The method of claim 9, wherein the plant of lettuce line SV6881LG is the male parent. ### Claim 12 (depends on 9) An F1 hybrid seed produced by the method of claim 9. ### Claim 13 (depends on 12) An F1 hybrid plant produced by growing the seed of claim 12. ### Claim 14 A method for producing a seed of a line SV6881LG-derived lettuce plant comprising the steps of: (a) crossing a lettuce plant of line SV6881LG, a sample of seed of said line having been deposited under ATCC Accession Number PTA-121367, with a second lettuce plant; and (b) allowing seed of a SV6881LG-derived lettuce plant to form. ### Claim 15 (depends on 14) The method of claim 14, further comprising the steps of: (c) crossing a plant grown from said SV6881LG-derived lettuce seed with itself or a second lettuce plant to yield additional SV6881LG-derived lettuce seed; (d) growing said additional SV6881LG-derived lettuce seed of step (c) to yield additional SV6881LG-derived lettuce plants; and (e) repeating the crossing and growing steps of (c) and (d) to generate further SV6881LG-derived lettuce plants. ### Claim 16 A method of vegetatively propagating a plant of lettuce line SV6881LG comprising the steps of: (a) collecting tissue capable of being propagated from a plant of lettuce line SV6881LG, a sample of seed of said line having been deposited under ATCC Accession Number PTA-121367; and (b) producing at least a first rooted plant from said tissue. ### Claim 17 A process of producing a conversion of lettuce line SV6881LG comprising a new trait, the process comprising: (a) crossing a plant of lettuce line SV6881LG, wherein a sample of seed of said line has been deposited under ATCC Accession Number PTA-121367, with a lettuce plant that comprises a new trait to produce progeny seed; (b) harvesting and planting the progeny seed to produce at least one progeny plant of a subsequent generation, wherein the progeny plant comprises the new trait; (c) crossing the progeny plant with a plant of lettuce line SV6881LG to produce backcross progeny seed; (d) harvesting and planting the backcross progeny seed to produce at least one backcross progeny plant; and (e) repeating steps (c) and (d) for at least three additional generations to produce a converted plant of lettuce line SV6881LG, wherein the converted plant of lettuce line SV6881LG comprises the new trait. ### Claim 18 (depends on 17) A converted lettuce plant produced by the method of claim 17. ### Claim 19 A method of producing a plant of lettuce line SV6881LG comprising an added desired trait, the method comprising introducing a transgene conferring the desired trait into a plant of lettuce line SV6881LG, wherein a sample of seed of said line has been deposited under ATCC Accession Number PTA-121367. ### Claim 20 (depends on 19) A plant produced by the method of claim 19. ### Claim 21 (depends on 2) A method of producing food comprising: (a) obtaining the plant of claim 2, and (b) collecting leaf tissue from the plant, wherein the leaf tissue is capable of use as food.
