Abstract

The present invention relates to a lettuce plant (Lactuca sativa L.) resistant against Nasonovia ribisnigri biotype 1 (Nr:1) representative seeds of which were deposited under NCIMB accession number 41763. Such a lettuce plant may be obtainable by crossing a lettuce plant with a plant grown from seeds of seedlot 10G.913569 representative seeds of which were deposited with the NCIMB under NCIMB accession number 41763 and selecting preferably in the F2 progeny of the cross for plants being resistant against Nasonovia ribisnigri biotype 1 (Nr:1).

Claims

1. A lettuce plant (Lactuca sativa L.) having in its genome a genetic determinant that confers resistance against Nasonovia ribisnigri biotype 1 (Nr:

1), which genetic determinant is as present in seeds of which a representative sample was deposited under NCIMB accession number 41763.

2. A lettuce plant as claimed in claim 1 having in its genome a genetic determinant that confers resistance against Nasonovia ribisnigri biotype 1 (Nr:

1), which plant is obtainable by crossing a plant grown from seeds of seed lot 10G.913569, representative seeds of which were deposited with the NCIMB under NCIMB accession number 41763, with another plant and selecting preferably in the F2 progeny of the cross for plants being resistant against Nasonovia ribisnigri biotype 1 (Nr;

1).

3. A lettuce plant as claimed in claim 1, being resistant against Nr:

1 as compared to a susceptible control plant and having in its genome a genetic determinant that confers resistance against Nasonovia ribisnigri biotype 1 (Nr;

1), which plant is obtainable by crossing a lettuce plant with a plant grown from seeds of seed lot 10G.913569, representative seeds of which were deposited with the NCIMB under NCIMB accession number 41763, and selecting in the F2 progeny of the cross that is obtained after selfing the F1 for plants being resistant against Nr;

1.

4. A seed of a lettuce plant as claimed in claim 1, wherein a lettuce plant that is grown from the seed is resistant against Nr:

1 as a result of the presence in its genome of a genetic determinant that confers resistance against Nasonovia ribisnigri biotype 1 (Nr;

1), which determinant is as present in seeds having NCIMB accession number 41763.

5. A progeny of a plant or seed as claimed in claim 1, which progeny is resistant against Nr:

1 as a result of the presence in its genome of a genetic trait that confers resistance against Nasonovia ribisnigri biotype 1 (Nr;

1) as present in seeds having NCIMB accession number 41763.

6. A propagation material of a plant as claimed in claim 1, suitable for sexual reproduction, in particular microspores, pollen, ovaries, ovules, embryo sacs and egg cells, wherein the propagation material carries the genetic trait that confers resistance against Nasonovia ribisnigri biotype 1 (Nr:

1) as present in seeds having NCIMB accession number 41763.

7. Plant parts of a plant as claimed in claim 1, suitable for vegetative reproduction, in particular cuttings, roots, stems, cells, protoplasts, and tissue culture, wherein the propagation material carries the genetic trait that confers resistance against Nasonovia ribisnigri biotype 1 (Nr:

1) as found in seeds having NCIMB accession number 41763.

8. A head of a lettuce plant as claimed in claim 1, which lettuce plant is resistant against Nasonovia ribisnigri biotype 1 (Nr:

1) as a result of the presence in its genome of a genetic determinant that confers resistance against Nasonovia ribisnigri biotype 1 (Nr;

1), which determinant is as present in seeds having NCIMB accession number 41763.

9. A food product, comprising the head of a lettuce plant of claim 8 or parts thereof.

10. The food product as claimed in claim 9, wherein the parts are leaves or parts thereof.

11. A method of conferring resistance against Nasonovia ribisnigri biotype 1 (Nr:

1) to plants that are susceptible to Nasonovia ribisnigri biotype 1 (Nr;

1) comprising breeding Lactuca sativa 10G.913569, representative seeds of which were deposited under NCIMB accession number 41763, to the plants that are susceptible to Nasonovia ribisnigri biotype 1 (Nr;

1), thereby conferring resistance against Nasonovia ribisnigri biotype 1 (Nr;

1) to plants that are susceptible to Nasonovia ribisnigri biotype 1 (Nr;

1).
