Abstract

A potato cultivar designated E12 is disclosed. The invention relates to the tubers of potato cultivar E12, to the seeds of potato cultivar E12, to the plants of potato E12, to the plant parts of potato cultivar E12, to food products produced from potato cultivar E12, and to methods for producing a potato plant produced by crossing potato cultivar E12 with itself or with another potato variety. The invention also relates to methods for producing a potato plant containing in its genetic material one or more transgenes and to the transgenic potato plants and plant parts produced by those methods. This invention also relates to potato cultivars or breeding cultivars and plant parts derived from potato variety E12, to methods for producing other potato cultivars, lines or plant parts derived from potato cultivar E12 and to the potato plants, varieties, and their parts derived from use of those methods. The invention further relates to hybrid potato tubers, seeds, plants and plant parts produced by crossing potato cultivar E12 with another potato cultivar.

First claim

What is claimed is:

1. A potato tuber, or a part of a tuber, of potato cultivar E12, wherein a representative sample of said tuber was deposited under ATCC Accession No. PTA-120372.

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

3. A potato plant having all of the physiological and morphological characteristics of the plant of claim 2 , and comprising the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

4. A tissue culture of cells produced from the plant of claim 2 , wherein said cells of the tissue culture are produced from a plant part selected from the group consisting of leaf, pollen, embryo, cotyledon, hypocotyl, meristematic cell, root, root tip, pistil, anther, flowers, stem and tuber, and wherein said tissue cultured cells comprise the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

5. A potato plant regenerated from the tissue culture of claim 4 , wherein said plant has all of the physiological and morphological characteristics of potato cultivar E12.

6. A potato seed produced by growing the potato tuber, or a part of the tuber, of claim 1 , wherein said seed comprises the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

7. A potato plant, or a part thereof, produced by growing the seed of claim 6 .

8. A potato plant regenerated from tissue culture of the potato plant of claim 7 , wherein said regenerated plant comprises the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

9. A method for producing a potato seed, said method comprising crossing two potato plants and harvesting the resultant potato seed, wherein at least one potato plant is the potato plant of claim 2 .

10. A method for producing a potato seed, said method comprising crossing two potato plants and harvesting the resultant potato seed, wherein at least one potato plant is the potato plant of claim 7 .

11. A potato seed produced by the method of claim 10 , wherein said seed comprises the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

12. A potato plant, or a part thereof, produced by growing said potato seed of claim 11 .

13. A potato seed produced from the plant of claim 12 , wherein said seed comprises the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

14. The method of claim 9 , wherein one of said potato plants is transgenic and the other is potato cultivar E12.

15. The method of claim 10 , wherein one of said potato plants is transgenic and the other is potato cultivar E12.

16. A potato plant, or a part thereof, produced by growing the seed produced by the method of claim 14 , wherein said plant comprises the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

17. A method of introducing a desired trait into potato cultivar E12 , wherein the method comprises:
(a) crossing an E12 plant, wherein a representative sample of tubers was deposited under ATCC Accession No. PTA-120372, with a plant of another potato cultivar that comprises a desired trait to produce progeny plants, wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, modified fatty acid metabolism, modified carbohydrate metabolism and resistance to bacterial disease, fungal disease or viral disease;
(b) selecting one or more progeny plants that have the desired trait;
(c) backcrossing the selected progeny plants with E12 plants to produce backcross progeny plants;
(d) selecting for backcross progeny plants that have the desired trait; and
(e) repeating steps (c) and (d) two or more times in succession to produce selected third or higher backcross progeny plants that comprise the desired trait.

18. A potato plant produced by the method of claim 17 , wherein the plant has the desired trait and comprises the insert region of pSIM1278 that is present in cultivar E12 which contains inverted repeats of potato DNA effective for inhibition of expression of the endogenous asparagine synthetase-1 gene and the endogenous polyphenol oxidase-5 gene in addition to inverted repeats of the endogenous potato promoters for the phosphorylase-L and dikinase R1 genes.

19. The potato plant of claim 18 , 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.

20. The potato plant of claim 18 , wherein the desired trait is insect resistance and the insect resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.

21. The potato plant of claim 18 , wherein the desired trait is modified fatty acid metabolism or modified carbohydrate metabolism and said desired trait is conferred by a nucleic acid encoding a protein selected from the group consisting of fructosyltransferase, levansucrase, α-amylase, invertase and starch branching enzyme or DNA encoding an antisense of stearyl-ACP desaturase.

22. A method of producing a commodity plant product, comprising obtaining the plant of claim 2 , or a part thereof, and producing the commodity plant product from said plant or plant part thereof, wherein said commodity plant product is selected from the group consisting of French fries, potato chips, dehydrated potato material, potato flakes and potato granules.
