Abstract

The present invention relates to a Lactuca sativa seed designated 41-CO7708 RZ. The present invention also relates to a Lactuca sativa plant produced by growing the 41-CO7708 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 41-CO7708 RZ.

Claims (41)

1. A seed of lettuce variety 41-CO7708 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44049.

2. A lettuce plant grown from the seed of claim 1 .

3. A lettuce plant, or a part thereof, having all the physiological and morphological characteristics of the lettuce plant of claim 2 .

4. A part of the lettuce plant of claim 2 , wherein said part comprises a microspore, pollen, ovary, ovule, embryo sac, egg cell, cutting, root, stem, cell or protoplast.

5. A tissue culture of regenerable cells or protoplasts from the lettuce plant of claim 2 .

6. A lettuce plant regenerated from the tissue culture of claim 5 , wherein the regenerated plant expresses all of the physiological and morphological characteristics of lettuce variety 41-CO7708 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44049.

7. A method of vegetatively propagating a plant of lettuce variety 41-CO7708 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44049, comprising (a) collecting tissue capable of being propagated from a lettuce plant of claim 2 , (b) cultivating the tissue to obtain proliferated shoots and rooting the proliferated shoots to obtain rooted plantlets, and (c) optionally growing plants from the rooted plantlets.

8. A method for producing a progeny plant of lettuce cultivar 41-CO7708 RZ, comprising crossing a lettuce plant of claim 2 with itself or with another lettuce plant, harvesting the resultant seed, and growing said seed.

9. A progeny plant produced by the method of claim 8 , wherein said progeny exhibits all the morphological and physiological characteristics of the lettuce variety designated 41-CO7708 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44049.

10. A lettuce plant of lettuce variety 41-CO7708 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44049, further comprising a transgene.

11. The plant as claimed in claim 10 , wherein the transgene is introduced via transformation.

12. A method for producing a modified lettuce plant comprising mutagenizing the seed of claim 1 and growing said seed.

13. A method for producing a modified lettuce plant comprising mutagenizing the plant of claim 2 .

14. A method for producing a modified lettuce plant comprising mutagenizing the plant of claim 3 .

15. A method for producing a modified lettuce plant comprising mutagenizing the plant of claim 7 .

16. A method for producing a modified lettuce plant comprising mutagenizing the part of plant of claim 3 .

17. A method for producing a modified lettuce plant comprising mutagenizing the part of plant of claim 4 .

18. A method for producing a modified lettuce plant comprising mutagenizing the tissue culture of claim 5 .

19. A method of producing a lettuce seed comprising crossing a male parent lettuce plant with a female parent lettuce plant and harvesting the resultant lettuce seed, wherein said male parent lettuce plant or said female parent lettuce plant is the lettuce plant of claim 2 .

20. An F1 lettuce seed produced by the method of claim 19 .

21. A lettuce plant produced by growing the seed of claim 20 .

22. A method for producing a seed of a 41-CO7708 RZ-derived lettuce plant comprising

(a) crossing a plant of lettuce variety 41-CO7708 RZ, a sample of seed of which having been deposited under NCIMB Accession No. 44049, with a second lettuce plant, and

(b) whereby seed of a 41-CO7708 RZ-derived lettuce plant forms.

23. The method of claim 22 further comprising

(c) crossing a plant grown from 41-CO7708 RZ-derived lettuce seed with itself or with a second lettuce plant to yield additional 41-CO7708 RZ-derived lettuce seed,

(d) growing the additional 41-CO7708 RZ-derived lettuce seed of step (c) to yield additional 41-CO7708 RZ-derived lettuce plants,

(e) repeating the crossing and growing of steps (c) and (d) for an additional 3-10 generations to generate further 41-CO7708 RZ-derived lettuce plants, and

(f) whereby seed of a 41-CO7708 RZ-derived lettuce plant forms.

24. A method of introducing at least one new trait into a plant of lettuce variety 41-CO7708 RZ comprising:

(a) crossing the plant of claim 2 , a sample of seed of which having been deposited under NCIMB Accession No. 44049, with a second lettuce plant that comprises at least one 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 at least one new trait,

(c) crossing the progeny plant with a plant of lettuce variety 41-CO7708 RZ to produce backcross progeny seed,

(d) harvesting and planting the backcross progeny seed to produce a backcross progeny plant, and

(e) repeating steps (c) and (d) for at least three additional generations to produce a lettuce plant of variety 41-CO7708 RZ comprising at least one new trait and all of the physiological and morphological characteristics of a plant of lettuce variety 41-CO7708 RZ, when grown in the same environmental conditions.

25. A lettuce plant produced by the method of claim 24 , wherein the plant comprises the at least one new trait and otherwise all of the physiological and morphological characteristics of a lettuce plant of lettuce variety 41-CO7708 RZ.

26. A method for producing lettuce leaves as a food product comprising

sowing the seed of claim 1 ,

growing the seed into a harvestable lettuce plant and

harvesting the head or leaves of said plant, optionally processing and/or packaging the head or the leaves.

27. A container comprising one or more lettuce plants of claim 2 for harvest of leaves.
