Triticale cultivar 343CMS and novel sequences for male sterility

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.
