Abstract

A novel sorghum variety designated R19D2759 and seed, plants, plant parts and plant cells thereof are produced from a cross of inbred sorghum varieties. Methods for producing a sorghum plant comprise crossing hybrid sorghum variety R19D2759 with another sorghum plant. Sorghum variety R19D2759, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of sorghum variety R19D2759 are provided. Methods for producing a sorghum plant containing in its genetic material one or more traits introgressed into sorghum variety R19D2759 include one or both of backcross conversion and transformation of one or both inbred parents. The sorghum seed, plants and plant parts produced thereby are described.

Claims (24)

1 . An F1 hybrid sorghum variety R19D2759 seed produced by crossing a first plant of variety 2PSKA12A with a second plant of variety 2PRQV78R, representative seed of the varieties 2PSKA12A and 2PRQV78R having been deposited under NCMA Accession Numbers 202510057 and 202510051, respectively.

2 . The F1 hybrid sorghum variety R19D2759 seed of claim 1 , further comprising a seed treatment on the seed.

3 . An F1 hybrid plant, plant part, or plant cell produced by growing the F1 hybrid sorghum variety R19D2759 seed of claim 1 , the plant part comprising at least one cell of sorghum variety R19D2759.

4 . The F1 hybrid plant, plant part, or plant cell of claim 3 , wherein the plant, plant part or plant cell is a pollen or ovule.

5 . A method of making a commodity plant product, the method comprising producing the commodity plant product from the plant or plant part of claim 3 .

6 . A method comprising cleaning the plant part of claim 3 , wherein the plant part comprises sorghum grain.

7 . A method for producing a second sorghum plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 3 to produce the second sorghum plant.

8 . A method comprising:

(a) crossing the plant or plant part of claim 3 with itself or a different plant to produce progeny seed;

(b) growing the progeny seed to produce a progeny plant and crossing the progeny plant with itself or a different plant to produce further progeny seed.

9 . A method comprising generating a molecular marker profile from markers bound to nucleic acids isolated from the hybrid sorghum variety R19D2759 plant, plant part, or plant cell of claim 3 .

10 . A seed of F1 hybrid sorghum variety R19D2759 further comprising a locus conversion, wherein the seed is produced by crossing a first plant of variety 2PSKA12A with a second plant of variety 2PRQV78R; wherein representative seed of the varieties 2PSKA12A and 2PRQV78R have been deposited under NCMA Accession Numbers 202510057 and 202510051, respectively; and wherein at least one of the varieties 2PSKA12A and 2PRQV78R further comprises the locus conversion which is inherited by the seed, and wherein the seed produces a plant which otherwise has all the morphological and physiological characteristics as sorghum variety R19D2759 when grown under the same environmental conditions.

11 . The seed of claim 10 , further comprising a seed treatment on the seed.

12 . The seed of claim 10 , wherein the locus conversion confers a property selected from the group consisting of male sterility, site-specific recombination, abiotic stress tolerance, altered phosphate, altered antioxidants, altered fatty acids, altered essential amino acids, altered carbohydrates, herbicide tolerance, insect resistance and disease resistance.

13 . A method comprising generating a molecular marker profile from markers bound to nucleic acids isolated from the hybrid sorghum variety R19D2759 seed of claim 10 .

14 . An F1 hybrid plant, plant part, or plant cell produced by growing the seed of claim 10 , wherein the plant part comprises at least one cell of hybrid sorghum variety R19D2759 further comprising a locus conversion.

15 . A method comprising cleaning the plant part of claim 14 , wherein the plant part comprises sorghum grain.

16 . The F1 hybrid plant, plant part, or plant cell of claim 14 , wherein the plant, plant part or plant cell is a pollen or ovule.

17 . A method of making a commodity plant product, the method comprising producing the commodity plant product from the plant or plant part of claim 14 .

18 . A method for producing a second sorghum plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 14 to produce the second sorghum plant.

19 . A method comprising:

(a) crossing the plant or plant part of claim 14 with itself or a different plant to produce progeny seed;

(b) growing the progeny seed to produce a progeny plant and crossing the progeny plant with itself or a different plant to produce further progeny seed.

20 . A seed of F1 hybrid sorghum variety R19D2759 further comprising a first single locus conversion, produced by crossing a first plant of variety 2PSKA12A with a second plant of variety 2PRQV78R, wherein representative seed of said varieties 2PSKA12A and 2PRQV78R have been deposited under NCMA Accession numbers 202510057 and 202510051, respectively, and wherein one or both of the first plant and second plant further comprises the single locus conversion, and wherein a plant grown from said seed comprises a trait conferred by said first single locus conversion, and otherwise comprises all the morphological and physiological characteristics as F1 sorghum variety R19D2759 when grown under the same environmental conditions.
