## Abstract

A novel maize variety designated X13H923 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 X13H923 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X13H923 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the maize variety X13H923, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X13H923. This invention further relates to methods for producing maize varieties derived from maize variety X13H923.

## Claims

### Claim 1

A seed of hybrid maize variety X13H923, representative seed produced by crossing a first plant of variety PH2558 with a second plant of variety PH24VK, wherein representative seed of the varieties PH2558 and PH24VK have been deposited under ATCC Accession Numbers PTA-123180 and PTA-123566, respectively.

### Claim 2 (depends on 1)

A plant of hybrid maize variety X13H923 grown from the seed of claim 1.

### Claim 3 (depends on 2)

A plant part or cell of the plant of claim 2, wherein the plant part comprises at least one cell of hybrid maize variety X13H923.

### Claim 4 (depends on 1)

A method of producing the seed of claim 1, the method comprising crossing a plant of variety PH2558 with a plant of variety PH24VK, wherein representative seed of varieties PH2558 and PH24VK have been deposited under ATCC Accession numbers PTA-123180 and PTA-123566, respectively.

### Claim 5

A seed of hybrid maize variety X13H923 further comprising a single locus conversion, representative seed of hybrid maize variety X13H923 produced by crossing a first plant of variety PH2558 with a second plant of variety PH24VK, wherein representative seed of the varieties PH2558 and PH24VK have been deposited under ATCC Accession Numbers PTA-123180 and PTA-123566, respectively.

### Claim 6 (depends on 5)

The seed of claim 5, wherein the locus conversion comprises a transgene conferring 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.

### Claim 7 (depends on 5)

The hybrid maize variety X13H923 seed of claim 5, further comprising a seed treatment on the surface of the seed.

### Claim 8 (depends on 5)

A method for producing nucleic acids, the method comprising isolating nucleic acids from the hybrid maize variety X13H923 seed of claim 5.

### Claim 9 (depends on 5)

A plant grown from the seed of claim 5.

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 9)

A method for producing a second maize plant, the method comprising doubling haploid seed generated from a cross of the maize plant of claim 9 with a different maize plant.

### Claim 12

An F1 hybrid maize variety X13H923 seed further comprising a locus conversion, the seed being produced by crossing a first plant of variety PH2558 with a second plant of variety PH24VK; representative seed of the varieties PH2558 and PH24VK having been deposited under ATCC Accession Numbers PTA-123180 and PTA-123566, respectively; wherein at least one of the varieties PH2558 and PH24VK further comprises a locus conversion and wherein the seed produces a plant having otherwise all the physiological and morphological characteristics as maize variety X13H923 when grown under the same environmental conditions.

### Claim 13 (depends on 12)

The seed of claim 12, further comprising a seed treatment on the surface of the seed.

### Claim 14 (depends on 12)

The seed of claim 12, wherein the 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.

### Claim 15 (depends on 12)

A method for producing nucleic acids, the method comprising isolating nucleic acids from the seed of claim 12.

### Claim 16 (depends on 12)

A plant, plant part, or plant cell produced by growing the seed of claim 12, the plant, plant part or plant cell comprising at least one F1 hybrid maize variety X13H923 cell.

### Claim 17 (depends on 16)

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

### Claim 18 (depends on 16)

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.

### Claim 19 (depends on 16)

A method for producing a second maize plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 16 to produce the second maize plant.

### Claim 20 (depends on 16)

A method for producing a second maize plant, the method comprising doubling haploid seed generated from a cross of the maize plant or plant part of claim 16 with a different maize plant.
