Abstract

A novel maize variety designated 1PYKM89 and seed, plants and plant parts thereof are provided. Methods for producing a maize plant comprise crossing maize variety 1PYKM89 with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into 1PYKM89 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby are provided. Hybrid maize seed, plants or plant parts are produced by crossing the variety 1PYKM89 or a locus conversion of 1PYKM89 with another maize variety.

Claims (20)

1 . A seed, plant, plant part, or plant cell of maize line 1PYKM89, representative seed of the maize line 1PYKM89 having been deposited under NCMA accession number 202504017.

2 . The plant part of claim 1 , wherein the plant part is an embryo, ovule or pollen.

3 . An F1 hybrid maize seed produced by crossing the plant or plant part of claim 1 with a different maize plant.

4 . An F1 hybrid maize plant or plant part produced by growing the maize seed of claim 3 , wherein the plant part comprises at least one F1 hybrid maize plant cell.

5 . A method for producing a second maize plant, the method comprising applying plant breeding techniques to the F1 plant or plant part of claim 4 to produce the second maize plant.

6 . A method for producing a second maize plant or plant part, the method comprising doubling haploid seed generated from a cross of the plant or plant part of claim 4 with an inducer variety, thereby producing the second maize plant or plant part.

7 . A method of producing a modified seed, plant, plant part, or plant cell, the method comprising genome editing the seed, plant, plant part, or plant cell of claim 1 , thereby producing the modified seed, plant, plant part, or plant cell.

8 . A method for producing a second maize plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 1 to produce the second maize plant.

9 . A method of producing a modified progeny seed or a modified progeny plant, the method comprising providing the plant or plant part of claim 1 and (a) crossing or selfing the plant or plant part to produce a progeny seed and genome editing the progeny seed, or a progeny plant grown therefrom, to produce the modified progeny seed or the modified progeny plant; or (b) genome editing the plant or plant part to produce a modified plant or a modified seed grown thereon and crossing or selfing the modified plant, or a modified plant grown from the modified seed to produce the modified progeny seed or the modified progeny plant grown therefrom.

10 . A method for producing nucleic acids, the method comprising isolating nucleic acids from the seed, plant, plant part, or plant cell of claim 1 .

11 . A seed, or plant of maize line 1PYKM89 further comprising a single locus conversion, wherein representative seed of maize line 1PYKM89 have been deposited under NCMA accession number 202504017, and wherein the plant or a plant grown from the seed otherwise comprises all of the physiological and morphological characteristics of maize line 1PYKM89.

12 . The seed or plant of claim 11 , wherein the single locus conversion confers a property selected from the group consisting of male sterility, a site for site-specific recombination, abiotic stress tolerance, altered phosphate content, altered antioxidant content, altered fatty acid content, altered essential amino acid content, altered carbohydrate content, herbicide tolerance, insect resistance and disease resistance.

13 . An F1 hybrid maize seed produced by crossing the plant of claim 11 with a different maize plant.

14 . An F1 hybrid maize plant produced by growing the seed of claim 13 .

15 . A method for producing a second maize plant, the method comprising applying plant breeding techniques to the F1 hybrid maize plant of claim 14 to produce the second maize plant.

16 . A method of making a commodity plant product comprising silage, starch, fat, syrup or protein, the method comprising producing the commodity plant product from the F1 hybrid maize of claim 14 .

17 . A method for producing nucleic acids, the method comprising isolating nucleic acids from the seed or plant of claim 11 .

18 . A seed of maize line 1PYKM89, further comprising a transgene, wherein the transgene was introduced into maize line 1PYKM89 by backcrossing or genetic transformation, wherein a plant grown from the seed comprises a trait conferred by the transgene and otherwise comprises all of the physiological and morphological characteristics of maize line 1PYKM89, and wherein representative seeds of maize line 1PYKM89 have been deposited under NCMA Accession No. 202504017.

19 . A method of producing a maize progeny seed, the method comprising crossing a maize plant grown from the seed of claim 18 with itself or a second maize plant to produce the maize progeny seed.

20 . A method of making a commodity plant product comprising silage, starch, fat, syrup or protein, the method comprising producing the commodity plant product from a maize plant or maize plant part grown from a maize seed produced from a cross of a plant grown from the maize seed of claim 18 with a plant of a different maize line.
