9 . A plant part of the plant of claim 8 , wherein the plant part comprises at least one cell of said plant.
10 . The plant part of claim 9 , selected from the group consisting of awn, leaf, pollen, ovule, embryo, cotyledon, hypocotyl, meristematic cell, root, root tip, pistil, anther, floret, seed, pericarp, spike, stem, or callus.
11 . A tissue culture produced from the plant part of claim 9 .
12 . A wheat plant regenerated from the tissue culture of claim 11 , wherein the wheat plant comprises the physiological and morphological characteristics of variety OK15MASBx7 ARS 8-20.
13 . A wheat plant, or part thereof, having all the physiological and morphological characteristics of the wheat plant of claim 8 .
14 . A seed of wheat variety OK15MASBx7 ARS 8-20, wherein a representative sample of seed of said variety has been deposited under NCMA Accession No. 20261016.
15 . A composition comprising the seed of claim 14 comprised in plant seed growth media, wherein a representative sample of seed of said variety has been deposited under NCMA Accession No. 20261016.
16 . A method of producing wheat seed, wherein the method comprises crossing the plant of claim 8 with itself or a second wheat plant.
17 . The method of claim 16 , wherein the method comprises crossing the plant of wheat variety OK15MASBx7 ARS 8-20 with a second, distinct wheat plant and producing an F 1 hybrid seed.
18 . The wheat seed produced by the method of claim 16 .
19 . An F 1 hybrid wheat plant or plant part produced by growing the seed of claim 18 .
20 . The method of claim 17 , wherein the method further comprises:
(a) crossing a plant grown from said F 1 hybrid seed with itself or a different wheat plant to produce a seed of a progeny plant of a subsequent generation; (b) growing a progeny plant of the subsequent generation from said seed of a progeny plant of the subsequent generation and crossing the progeny plant of the subsequent generation with itself or a second plant to produce a progeny plant of a further subsequent generation; and (c) repeating steps (a) and (b) using said progeny plant of the further subsequent generation from step (b) in place of the plant grown from said F 1 hybrid wheat seed in step (a), wherein steps (a) and (b) are repeated with sufficient inbreeding to produce an inbred wheat plant derived from the wheat variety OK15MASBx7 ARS 8-20.
21 . A method of introducing a desired trait into wheat variety OK15MASBx7 ARS 8-20 comprising: (a) crossing the wheat variety OK15MASBx7 ARS 8-20 plant of claim 12 with another wheat plant that comprises a desired trait to produce F 1 progeny plants; (b) selecting one or more progeny plants that have the desired trait; (c) crossing the selected progeny plants with wheat variety OK15MASBx7 ARS 8-20 plants to produce backcross progeny plants; (d) selecting for backcross progeny plants that have the desired trait; and (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher 61 backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of wheat variety OK15MASBx7 ARS 8-20 when grown in the same environmental conditions as wheat variety OK15MASBx7 ARS 8-20.
