Triticale cultivar 343CMS and novel sequences for male sterility
A cytoplasmic male sterile triticale cultivar, designated 343CMS, is disclosed. The invention relates to the seeds of triticale cultivar 343CMS, to the plants of triticale 343CMS, and to methods for producing a triticale plant produced by crossing the cultivar 343CMS with itself or another triticale variety. The invention also relates to methods for producing a triticale plant containing in its genetic material one or more transgenes and to the transgenic triticale plants and plant parts produced by those methods. The invention also relates to triticale varieties or breeding varieties and plant parts derived from triticale cultivar 343CMS, to methods for producing other triticale varieties, lines or plant parts derived from triticale cultivar 343CMS, and to the triticale plants, varieties, and their parts derived from the use of those methods. The invention further relates to hybrid triticale seeds and plants produced by crossing the cultivar 343CMS with another triticale cultivar.
1. A seed of triticale cultivar 343CMS, wherein a representative sample of seed of said cultivar has been deposited under ATCC Accession No. PTA-126905.
2. A triticale plant, or a part thereof, produced by growing the seed of claim 1 .
3. 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 heads, awns, leaves, pollen, embryos, cotyledons, hypocotyls, meristematic cells, roots, root tips, pistils, anthers, flowers, stems, and calli.
4. A protoplast produced from the plant of claim 2 .
5. A protoplast produced from the tissue culture of claim 3 .
6. A triticale plant regenerated from the tissue culture of claim 3 , wherein the plant has all of the morphological and physiological characteristics of cultivar 343CMS wherein a representative sample of seed was deposited under ATCC Accession No. PTA-126905.
7. A method for producing an F 1 triticale seed, wherein the method comprises crossing the plant of claim 2 with a different triticale plant or a plant of 343CMS having restored male fertility and harvesting the resultant F 1 hybrid triticale seed.
8. A The F 1 hybrid triticale seed produced by the method of claim 7 .
9. A triticale plant, or a part thereof, produced by growing said seed of claim 8 .
10. An F 1 hybrid triticale plant or part thereof produced by crossing the triticale plant of claim 2 , with a different triticale plant.
11. A method of introducing a desired trait into triticale cultivar 343CMS wherein the method comprises: (a) crossing a 343CMS plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-126905, with a plant of another triticale 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, modified phytic metabolism, modified waxy starch content, modified gluten content and resistance to bacterial disease, fungal disease or viral disease; (b) selecting one or more progeny plants that have the desired trait to produce selected progeny plants; (c) crossing the selected progeny plants with the 343CMS plants to produce backcross progeny plants; (d) selecting for backcross progeny plants that have the desired trait and are otherwise phenotypically indistinguishable from triticale cultivar 343CMS listed in Table 1 to produce selected backcross progeny plants; and (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and are otherwise phenotypically indistinguishable from triticale cultivar 343CMS.
12. A triticale plant or plant part produced by the method of claim 11 , wherein the plant has the desired trait and is otherwise phenotypically indistinguishable from triticale cultivar 343CMS.
13. A method of introducing male sterility into a desired triticale or wheat plant wherein the method comprises: (a) crossing a 343CMS plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-126905, with the triticale or wheat plant to produce at least one progeny plant.
14. An F 1 male sterile plant produced by the method of claim 13 .
15. The F 1 male sterile plant of claim 14 , wherein the plant comprises the polynucleotide of SEQ ID NO: 64, 66, or 68.
16. The F 1 male sterile plant of claim 14 , wherein the plant is a triticale plant.
17. The F 1 male sterile plant of claim 14 , wherein the plant is a wheat plant.
18. The method of claim 13 , further comprising the steps of: (b) selecting one or more progeny plants that have the male sterility trait to produce selected progeny plants; and (c) using the selected progeny plants as a source of breeding material to develop further progeny plants.
19. The method of claim 13 , further comprising: assaying one or more progeny plants for the presence of the polynucleotide of SEQ ID NO: 64, 66, or 68.
20. A triticale or wheat plant comprising a mitochondrial polynucleotide associated with cytoplasmic male sterility as present in triticale cultivar 343CMS, wherein a representative sample of seed of the cultivar has been deposited under ATCC Accession No. PTA-126905, and wherein the plant is an F 1 progeny of triticale cultivar 343CMS.
21. The triticale or wheat plant of claim 20 , wherein the plant comprises the polynucleotide of SEQ ID NO: 64, 66, or 68.
