Abstract

The present invention relates to a Lactuca sativa seed designated 45-IC3262 RZ. The present invention also relates to a Lactuca sativa plant produced by growing the 45-IC3262 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 45-IC3262 RZ.

Claims (23)

1. A seed of lettuce variety 45-IC3262 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44096.

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 leaf, cotyledon, hypocotyl, meristematic cell, microspore, pollen, ovary, ovule, embryo, embryo sac, egg cell, cutting, root, root tip, anther, flower, stem, cell, seed 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 45-IC3262 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44096.

7. A method of vegetatively propagating a plant of lettuce variety 45-IC3262 RZ comprising (a) collecting tissue capable of being propagated from the 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 variety 45-IC3262 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44096, comprising crossing the 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 45-IC3262 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44096.

10. A lettuce plant grown from a seed of lettuce variety 45-IC3261 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44096, 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 or 3 .

14. A method for producing a modified lettuce plant comprising mutagenizing the part of plant of claim 3 or 4 .

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

16. 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 .

17. An F1 lettuce seed produced by the method of claim 16 .

18. A lettuce plant produced by growing the seed of claim 17 .

19. A method for producing a seed of a 45-IC3262 RZ-derived lettuce plant comprising (a) crossing a plant of lettuce variety 45-IC3262 RZ, a sample of seed of which having been deposited under NCIMB Accession No. 44096, with a second lettuce plant, and (b) whereby seed of a 45-IC3262 RZ-derived lettuce plant forms.

20. The method of claim 19 further comprising (c) crossing a plant grown from 45-IC3262 RZ-derived lettuce seed with itself or with a second lettuce plant to yield additional 45-IC3262 RZ-derived lettuce seed, (d) growing the additional 45-IC3262 RZ-derived lettuce seed of step (c) to yield additional 45-IC3262 RZ-derived lettuce plants, and (e) repeating the crossing and growing of steps (c) and (d) for an additional 3-10 generations to generate further 45-IC3262 RZ-derived lettuce plants, and (f) whereby seed of a 45-IC3262 RZ-derived lettuce plant forms.

21. A method of introducing at least one new trait into a plant of lettuce variety 45-IC3262 RZ comprising: (a) crossing the lettuce plant of claim 2 , a sample of seed of which having been deposited under NCIMB Accession No. 44096, 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 45-IC3262 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 45-IC3262 RZ comprising at least one new trait and all of the physiological and morphological characteristics of a plant of lettuce variety 45-IC3262 RZ, when grown in the same environmental conditions.

22. A method for producing lettuce leaves as a food product comprising sowing the seed of claim 1 and 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.

23. A container comprising the lettuce plant of claim 2 for harvest of leaves.
