Abstract

The present invention relates to a lettuce variety NUN 7824 LT (referred to as “Salmon”) having resistance against downy mildew (Bremia lactucae) and lettuce aphid (Nasonovia ribisnigri) and which has very intense red colored and glossy leaves. The invention further relates to methods for producing the new lettuce variety and representative seed having been deposited under Accession No. NCIMB ______.

Claims

1. A lettuce plant designated NUN 7824 LT, referred to as Salmon, representative seed of which having been deposited under Accession Number NCIMB ______.

3. A part of the plant of claim 1, wherein the part is a leaf or a part thereof.

4. A part of the plant of claim 1, wherein said part of the plant is suitable for vegetative reproduction.

5. A part of the plant of claim 1, wherein said part of the plant is suitable for sexual reproduction.

6. A cell or tissue culture of the lettuce plant of claim 1.

8. A lettuce plant that has resistance against downy mildew BL:

1 to BL;

27, resistance against lettuce aphid Nr;

0 and very intensive red colored mature leaves, which is regenerated from the part of the plant of claim 4.

9. A lettuce plant that has resistance against downy mildew BL:

1 to BL;

27, resistance against lettuce aphid Nr;

0 and very intensive red colored mature leaves, which is regenerated from the cell or tissue culture of claim 6.

10. A method of producing a lettuce plant, comprising crossing the plant of claim 1 with a second lettuce plant one or more times, and selecting progeny from said crossing.

11. A method of producing a lettuce plant, comprising selfing the plant of claim 1 one or more times, and selecting progeny from said selfing.

17. Package comprising leaves or parts thereof of a plant of claim 3.

18. Package comprising leaves or parts thereof of a plant of claim 3.

21. A food or feed product comprising a plant part of claim 1.

2. A seed designated NUN 7824 LT, representative seed having been deposited under Accession Number NCIMB ______.

7. A lettuce plant that has resistance against downy mildew (Bremia lactucae Regal) BL:

1 to BL;

27, resistance against lettuce aphid (Nasonovia ribisnigri) Nr;

0 and very intensive red colored mature leaves and which is grown from the seed of claim 2.

19. Package comprising the seed of claim 2.

20. Seed pellet comprising the seed of claim 2.

12. Progeny of lettuce variety designated NUN 7824 LT obtained by further breeding with said variety, wherein said progeny has at least the essential physiological and morphological characteristics of the variety designated NUN 7824 LT selected from the group consisting of resistance against downy mildew BL:

1 to BL;

27, resistance against lettuce aphid Nr0 and very intensive red colored mature leaves.

13. The progeny of claim 12, wherein said progeny further has at least one of the physiological and morphological characteristic selected from the group consisting of white to silver grey seed color, broad shape of cotyledons (according to USDA descriptors), higher concentration of anthocyanin in fourth leaves compared to lettuce variety Sadawi, glossy mature leaves (according to USDA descriptors), higher average head weight of at least 5% at mature harvest stage compared to the average head weight of lettuce variety Sadawi at the same mature harvest stage, when grown under the same conditions.

14. An Essentially Derived Variety having at least one, two or three physiological and/or morphological characteristics which are different from those of NUN 7824 LT and which otherwise has the essential physiological and morphological characteristics of a lettuce plant designated NUN 7824 LT selected from the group consisting of resistance against downy mildew BL:

1 to BL;

27, resistance against lettuce aphid Nr;

0 and very intensive red colored mature leaves.

15. A method of producing a hybrid lettuce seed, comprising crossing a first parent lettuce plant with a second parent lettuce plant and harvesting the resultant hybrid lettuce seed, wherein said first parent lettuce plant or said second parent lettuce plant is a lettuce plant designated NUN 7824 LT.

16. A hybrid lettuce plant produced from crossing a first parent lettuce plant with a second parent lettuce plant and harvesting the resultant hybrid lettuce seed, wherein said first parent lettuce plant or said second parent lettuce plant is a lettuce plant designated NUN 7824 LT.

22. A method of introducing a single locus conversion into a lettuce plant designated NUN 7824 LT comprising

(a) crossing a plant of variety designated NUN 7824 LT with a second plant comprising a desired single locus to produce F1 progeny plants;

(b) selecting F1 progeny plants that have the single locus to produce selected F1 progeny plants;

(c) crossing the selected progeny plants with at least a first plant designated NUN 7824 LT to produce backcross progeny plants;

(d) selecting backcross progeny plants that have the single locus and essential physiological and morphological characteristics of a plant designated NUN 7824 LT to produce selected backcross progeny plants; and

(e) repeating steps (c) and (d) one or more times in succession to produce selected second or higher backcross progeny plants that comprise the single locus and otherwise comprise at least the essential physiological and morphological characteristics of a plant designated NUN 7824 LT.

23. The method of claim 22, wherein the single locus confers a trait, wherein the trait is pest resistance or disease resistance.

24. The method of claim 23, wherein the single locus confers a trait, wherein the trait is resistance against Nasonovia ribisnigri Nr:
