Cotton variety ST 5115GLT

1. A seed of cotton variety ST 5115GLT, wherein a representative seed of said variety was deposited under American Type Culture Collection (ATCC) Accession No. PTA-125007.

2. A plant, or a regenerable part thereof, produced by growing the seed of claim 1 .

3. A plant, or a regenerable part thereof, obtained by vegetative reproduction from the plant, or a part thereof, of claim 2 , wherein said plant, or a part thereof, has all of the physiological and morphological characteristics of cotton variety ST 5115GLT, a sample of seed of cotton variety ST 5115GLT having been deposited under ATCC Accession No. PTA-125007.

4. A process of vegetative reproduction of cotton variety ST 5115GLT comprising culturing regenerable cells or tissue from ST 5115GLT, a sample of seed of cotton variety ST 5115GLT having been deposited under ATCC Accession No. PTA-125007.

5. A cell or tissue culture produced from the plant, or a part thereof, of claim 2 .

6. A cotton plant regenerated from the cell or tissue culture of claim 5 , wherein said plant has all of the physiological and morphological characteristics of ST 5115GLT, a sample of seed of cotton variety ST 5115GLT having been deposited under ATCC Accession No. PTA-125007.

7. A method of producing an F1 hybrid cotton seed, comprising the steps of crossing the plant of claim 2 with a different cotton plant and harvesting the resultant F1 hybrid cotton seed.

8. An F1 hybrid cotton seed produced by the method of claim 7 .

9. An F1 hybrid cotton plant, or a regenerable part thereof, produced by growing the hybrid seed of claim 8 .

10. A method of introducing a desired trait into a cotton plant, the method comprising transforming the plant of claim 2 with a transgene that confers the desired trait, wherein the transformed plant otherwise retains all the physiological and morphological characteristics of cotton variety ST 5115GLT and contains the desired trait.

11. The method of claim 10 , wherein said desired trait is fiber quality, herbicide resistance, insect resistance, bacterial disease resistance or fungal disease resistance.

12. A method of introducing a desired trait into a cotton plant, the method comprising transforming the plant of claim 9 with a transgene that confers the desired trait, wherein the transformed plant retains all the physiological and morphological characteristics of cotton variety ST 5115GLT and contains the desired trait, seed of cotton variety ST 5115GLT having been deposited as ATCC Accession No. PTA-125007.

13. A cotton plant produced by the method of claim 10 .

14. A method of introducing a single locus conversion into cotton variety ST 5115GLT comprising:

(a) crossing a plant of variety ST 5115GLT 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 of variety ST 5115GLT to produce backcross progeny plants;

(d) selecting backcross progeny plants that have the single locus and otherwise comprise all of the physiological and morphological characteristics of cotton variety ST 5115GLT 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 all of the physiological and morphological characteristics of cotton variety ST 5115GLT when grown in the same environmental conditions, a sample of seed of cotton variety ST 5115GLT having been deposited under ATCC Accession No. PTA-125007.

15. The method of claim 14 , wherein the single locus confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, pest resistance, disease resistance, modified fatty acid metabolism, modified carbohydrate metabolism, and modified cotton fiber characteristics.
