Acala ULTIMA EF cultivar plant and seed
View Patent ↗A cotton cultivar designated Acala ULTIMA EF is disclosed. The invention relates to the seeds of cotton cultivar Acala ULTIMA EF, to the plants and plant parts of cotton Acala ULTIMA EF and to methods for producing a cotton plant produced by crossing the cultivar Acala ULTIMA EF with itself or another cotton variety. The invention further relates to hybrid cotton seeds and plants produced by crossing the cultivar Acala ULTIMA EF with itself or with another cotton cultivar.
1. A seed of cotton cultivar designated Acala ULTIMA EF, representative seed of said cultivar having been deposited under ATCC Accession Number PTA-8218.
2. A cotton plant, or a regenerable part thereof, produced by growing the seed of claim 1 .
3. A tissue culture of regenerable cells produced from the plant of claim 2 .
4. A protoplast produced from the tissue culture of claim 3 .
5. The tissue culture of claim 3 , wherein cells of the tissue culture are from a plant part selected from the group consisting of leaf, pollen, embryo, root, root tip, anther, pistil, flower, seed, boll and stem.
6. A cotton plant regenerated from the tissue culture of claim 3 , said plant having all the morphological and physiological characteristics of cotton cultivar Acala ULTIMA EF, representative seed of said cultivar having been deposited under ATCC Accession Number PTA-8218.
7. A method for producing a hybrid cotton seed wherein the method comprises crossing the plant of claim 2 with a different cotton plant and harvesting the resultant hybrid cotton seed.
8. A hybrid cotton seed produced by the method of claim 7 .
9. A hybrid cotton plant, or a regenerable part thereof, produced by growing said hybrid seed of claim 8 .
10. A method of producing an herbicide resistant cotton plant wherein the method comprises transforming the cotton plant of claim 2 with a transgene that confers herbicide resistance.
11. An herbicide resistant cotton plant produced by the method of claim 10 .
12. The cotton plant of claim 11 , wherein the transgene confers resistance to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine and benzonitrile.
13. A method of producing an insect resistant cotton plant wherein the method comprises transforming the cotton plant of claim 2 with a transgene that confers insect resistance.
14. An insect resistant cotton plant produced by the method of claim 13 .
15. The cotton plant of claim 14 wherein the transgene encodes a Bacillus thuringiensis endotoxin.
16. A method of producing a disease resistant cotton plant wherein the method comprises transforming the cotton plant of claim 2 with a transgene that confers disease resistance.
17. A disease resistant cotton plant produced by the method of claim 16 .
18. A method of introducing a desired trait into cotton cultivar Acala ULTIMA EF wherein the method comprises:
crossing Acala ULTIMA EF plants grown from Acala ULTIMA EF seed, representative seed of which has been deposited under ATCC Accession Number PTA-8218, with plants of another cotton line that comprise a desired trait to produce progeny plants, wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance and disease resistance;
selecting progeny plants that have the desired trait to produce selected progeny plants;
crossing the selected progeny plants with the Acala ULTIMA EF plants to produce backcross progeny plants;
selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of cotton cultivar Acala ULTIMA EF to produce selected backcross progeny plants; and
repeating said crossing and selecting for backcross progeny plants steps at least three times in succession, or, when using molecular markers, repeating said crossing and selecting at least once and selfing said backcross progeny plants at least once, to produce respective selected fourth or higher backcross progeny plants or second-soiled backcross progeny plants that comprise the desired trait and essentially all of the physiological and morphological characteristics of cotton cultivar Acala ULTIMA EF.
19. A plant produced by the method of claim 18 , wherein the plant has the desired trait and essentially all of the physiological and morphological characteristics of cotton cultivar Acala ULTIMA EF as determined at the 5% significance level when grown in the same environmental conditions.
20. The plant of claim 19 wherein the desired trait is herbicide resistance and the resistance is conferred to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine and benzonitrile.
21. The plant of claim 19 wherein the desired trait is insect resistance and the insect resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.
22. A process of developing a cotton variety, comprising sequentially inbreeding segregating generations of a cotton hybrid having the plant of claim 2 as a parent until an advanced generation is attained, said advanced generation being F 5 or greater.
23. The process of claim 22 , in which inbreeding includes self-pollination.
