Abstract

A novel maize variety designated X17T129 and seed, plants and plant parts thereof are produced by crossing inbred maize varieties. Methods for producing a maize plant by crossing hybrid maize variety X17T129 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X17T129 through backcrossing or genetic transformation, and to the maize seed, plant and plant part produced thereby are described. Maize variety X17T129, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X17T129 are provided. Methods for producing maize varieties derived from maize variety X17T129 and methods of using maize variety X17T129 are disclosed.

Claims (19)

1 . A seed of hybrid maize X17T129 produced by crossing a first plant of maize line 1PTQT83 with a second plant of maize line 1PPBZ65, wherein representative seeds of the maize lines 1PTQT83 and 1PPBZ65 have been deposited under NCMA Accession Numbers 202212250 and 202207026, respectively.

2 . A plant or plant part of hybrid maize X17T129 grown from the seed of claim 1 , wherein the plant part comprises at least one hybrid maize X17T129 cell.

3 . A method of producing the seed of claim 1 , the method comprising crossing a plant of the maize line 1PTQT83 with a plant of the maize line 1PPBZ65.

4 . The seed of claim 1 , further comprising a transgene, wherein the transgene is introduced by backcrossing or genetic transformation into the maize line 1PTQT83, the maize line 1PPBZ65, or both maize lines 1PTQT83 and 1PPBZ65, and wherein a plant grown from the seed comprises the transgene and otherwise comprises all of the physiological and morphological characteristics of a plant of hybrid maize X17T129 when grown under the same environmental conditions.

5 . A seed of hybrid maize X17T129 further comprising a single locus conversion, wherein a plant grown from the seed comprises a trait conferred by the single locus conversion, wherein the seed is produced by crossing a first plant of maize line 1PTQT83 with a second plant of maize line 1PPBZ65, wherein the first plant, the second plant or both further comprise the single locus conversion, wherein representative seeds of the maize lines 1PTQT83 and 1PPBZ65 have been deposited under NCMA Accession Numbers 202212250 and 202207026, respectively.

6 . The hybrid maize X17T129 seed of claim 5 , wherein the single locus conversion confers a property selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

7 . The hybrid maize X17T129 seed of claim 5 , further comprising a seed treatment on the surface of the seed.

8 . A method for producing nucleic acids, the method comprising isolating nucleic acids from the hybrid maize X17T129 seed of claim 5 .

9 . A plant or plant part grown from the hybrid maize X17T129 seed of claim 5 , the plant part comprising at least one hybrid maize X17T129 cell further comprising the single locus conversion.

10 . A method of producing a commodity plant product comprising starch, syrup, silage, fat or protein, the method comprising producing the commodity plant product from the plant or plant part of claim 9 .

11 . A method for producing a second maize plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 9 to produce the second maize plant.

12 . A method for producing a hybrid maize X17T129 seed further comprising a locus conversion, the method comprising crossing a first plant of maize line 1PTQT83 with a second plant of maize line 1PPBZ65, representative seeds of the maize lines 1PTQT83 and 1PPBZ65 having been deposited under NCMA Accession Numbers 202212250 and 202207026, respectively, wherein at least one of the maize lines 1PTQT83 and 1PPBZ65 further comprises the locus conversion.

13 . The seed of claim 4 , further comprising a seed treatment on the surface of the seed.

14 . The seed of claim 4 , wherein the transgene confers a property selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

15 . A method for producing nucleic acids, the method comprising isolating nucleic acids from the seed of claim 4 .

16 . A plant or plant part produced by growing the seed of claim 4 , the plant part comprising at least one hybrid maize X17T129 cell further comprising the transgene.

17 . A method for producing nucleic acids, the method comprising isolating nucleic acids from the plant or plant part of claim 16 .

18 . A method of producing a commodity plant product comprising starch, syrup, silage, fat or protein, the method comprising producing the commodity plant product from the plant or plant part of claim 16 .

19 . A method for producing a second maize plant, the method comprising crossing the maize plant or plant part of claim 16 with itself or with a different maize plant.
