Abstract

The invention provides seed and plants of tomato hybrid DR4299TC and the parent lines thereof. The invention thus relates to the plants, seeds and tissue cultures of tomato hybrid DR4299TC and the parent lines thereof, and to methods for producing a tomato plant produced by crossing such plants with themselves or with another tomato plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of such plants, including the fruit and gametes of such plants.

14. The tissue culture according to claim 13, 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.

15. A tomato plant regenerated from the tissue culture of claim 13.

16. A method of vegetatively propagating the tomato plant of claim 1 comprising the steps of:

(a) collecting tissue capable of being propagated from the plant according to claim 1;

(b) cultivating said tissue to obtain proliferated shoots; and

(c) rooting said proliferated shoots to obtain rooted plantlets.

17. The method of claim 16, further comprising growing at least a first tomato plant from said rooted plantlets.

22. The plant of claim 1, further comprising a transgene.

23. The plant of claim 22, wherein the transgene confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, pest resistance, disease resistance, modified fatty acid metabolism, environmental stress tolerance, modified carbohydrate metabolism and modified protein metabolism.

24. The plant of claim 1, further comprising a single locus conversion.

25. The plant of claim 24, wherein the single locus conversion confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, pest resistance, disease resistance, modified fatty acid metabolism, environmental stress tolerance, modified carbohydrate metabolism and modified protein metabolism.

31. A plant part of the plant of claim 7.

32. The plant part of claim 31, further defined as a leaf, a flower, a fruit, an ovule, pollen, or a cell.

33. A method of producing a tomato seed comprising crossing the plant of claim 1 with itself or a second tomato plant and allowing seed to form.

34. A method of producing a tomato fruit comprising:

(a) obtaining the plant according to claim 1, wherein the plant has been cultivated to maturity; and

(b) collecting a tomato from the plant.

2. A tomato seed comprising at least a first set of the chromosomes of tomato line CHI-A808018 or tomato line CHD-A808019, a sample of seed of said lines having been deposited under ATCC Accession Number PTA-121436 and ATCC Accession Number PTA-121435, respectively.

5. The seed of claim 2, which is an inbred.

6. The seed of claim 2, which is a hybrid.

8. The seed of claim 6, defined as a seed of tomato hybrid DR4299TC, a sample of seed of said hybrid DR4299TC having been deposited under ATCC Accession Number PTA-121437.

9. The seed of claim 2, defined as a seed of line CHI-A808018 or line CHD-A808019.

18. A method of introducing a desired trait into a tomato line comprising:

(a) utilizing as a recurrent parent a plant of either tomato line CHI-A808018 or tomato line CHD-A808019, by crossing a plant of tomato line CHI-A808018 or tomato line CHD-A808019 with a second donor tomato plant that comprises a desired trait to produce F1 progeny, a sample of seed of said lines having been deposited under ATCC Accession Number PTA-121436, and ATCC Accession Number PTA-121435, respectively;

(b) selecting an Fl progeny that comprises the desired trait;

(c) backcros sing the selected F1 progeny with a plant of the same tomato line used as the recurrent parent in step (a), to produce backcross progeny;

(d) selecting backcross progeny comprising the desired trait and the physiological and morphological characteristics of the recurrent parent tomato line used in step (a); and

(e) repeating steps (c) and (d) three or more times to produce selected fourth or higher backcross progeny that comprise the desired trait, and otherwise comprise essentially all of the morphological and physiological characteristics of the recurrent parent tomato line used in step (a).

19. A tomato plant produced by the method of claim 18.

20. A method of producing a tomato plant comprising an added trait, the method comprising introducing a transgene conferring the trait into a plant of tomato hybrid DR4299TC, tomato line CHI-A808018 or tomato line CHD-A808019, a sample of seed of said hybrid and lines having been deposited under ATCC Accession Number PTA-121437, ATCC Accession Number PTA-121436, and ATCC Accession Number PTA-121435, respectively.

21. A tomato plant produced by the method of claim 20.

26. A method for producing a seed of a tomato plant derived from at least one of tomato hybrid DR4299TC, tomato line CHI-A808018 or tomato line CHD-A808019 comprising the steps of:
