Triticale cultivar APT1415420

A method of vegetatively propagating a plant of Triticale cultivar APT1415420, the method comprising:

• a. collecting tissue capable of being propagated from a plant of Triticale cultivar APT1415420, wherein a sample of seed of the cultivar was deposited under NCMA Accession No. 202509138;
• b. cultivating the tissue to obtain proliferated shoots to obtain rooted plantlets;
• and
• c. optionally growing plants from the rooted plantlets.

A method of introducing a desired trait into Triticale cultivar APT1415420 wherein the method comprises:

• a. crossing a APT1415420 plant, wherein a representative sample of seed was deposited under NCMA Accession No. 202509138, with a plant of another Triticale cultivar that comprises a desired trait to produce an F1 progeny plant;
• b. selecting one or more F1 progeny plants that have the desired trait to produce selected progeny plants;
• c. crossing the selected progeny plants with the APT1415420 plants to produce backcross progeny plants;
• d. selecting for backcross progeny plants that have the desired trait and otherwise all of the physiological and morphological characteristics of Triticale cultivar APT1415420 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 otherwise all of the physiological and morphological characteristics of Triticale cultivar APT1415420.
