Maize inbred PH42W8
A novel maize variety designated PH42W8 and seed, plants and plant parts thereof are provided. Methods for producing a maize plant comprise crossing maize variety PH42W8 with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PH42W8 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 PH42W8 or a locus conversion of PH42W8 with another maize variety.
1. A seed, plant, plant part, or plant cell of inbred maize variety PH42W8, representative seed of the variety having been deposited under ATCC accession number PTA-124808.
2. The plant part of claim 1 , wherein the plant part is an 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 seed produced by crossing a plant or plant part of inbred maize variety PH42W8, representative seed of the variety having been deposited under ATCC accession number PTA-124808 with a different maize plant, wherein inbred maize variety PH42W8 further comprises a transgene that is inherited by the seed, wherein the transgene was introduced into inbred maize variety PH42W8 by backcrossing or genetic transformation.
5. 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 cell of the F1 hybrid maize plant.
6. A method for producing a second maize plant, the method comprising applying plant breeding techniques to the F1 plant or plant part of claim 5 to produce the second maize plant.
7. 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 5 with an inducer variety, thereby producing the second maize plant or plant part.
8. 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 maize plant or plant part of claim 5 .
9. A method of producing a maize plant derived from the variety PH42W8, comprising:
a) crossing the plant of claim 1 with itself or a second plant to produce progeny seed;
b) growing the progeny seed to produce a progeny plant and crossing the progeny plant with itself or a different plant to produce further progeny seed; and
c) repeating step (b) for at least one additional generation to produce a maize plant derived from the variety PH42W8.
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 converted seed, plant, plant part or plant cell of inbred maize variety PH42W8, representative seed of the maize variety PH42W8 having been deposited under ATCC accession number PTA-124808, wherein the converted seed, plant, plant part or plant cell comprises a locus conversion, and wherein the plant or a plant grown from the converted seed, plant part or plant cell comprises the locus conversion and otherwise comprises the phenotypic characteristics of maize variety PH42W8 listed in Table 1 when grown under the same environmental conditions.
12. The converted seed, plant, plant part or plant cell of claim 11 , wherein the locus conversion confers a property selected from the group consisting of male sterility, site-specific recombination, abiotic stress tolerance, altered phosphate, altered antioxidants, altered fatty acids, altered essential amino acids, altered carbohydrates, herbicide tolerance, insect resistance and disease resistance.
13. A maize seed produced by crossing the plant or plant part of claim 11 with a different maize plant.
14. A hybrid maize plant or plant part produced by growing the seed of claim 13 , wherein the plant part comprises at least one cell of the hybrid maize plant.
15. A method for producing a second maize plant, the method comprising applying plant breeding techniques to the plant or plant part of claim 14 to produce the second maize plant.
16. 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 14 with an inducer variety, thereby producing the second maize plant or plant part.
17. 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 maize plant or plant part of claim 14 .
18. A method of producing a maize plant derived from the variety PH42W8, comprising:
a) crossing the plant of claim 11 with itself or a second plant to produce progeny seed;
b) growing the progeny seed to produce a progeny plant and crossing the progeny plant with itself or a different plant to produce further progeny seed; and
c) repeating steps (a) and (b) with sufficient inbreeding until a seed of an inbred maize plant derived from the variety PH42W8 is produced.
19. The method of claim 18 , further comprising crossing the inbred maize plant derived from the variety PH42W8 with a maize plant of a different genotype to produce seed of a hybrid plant derived from the maize variety PH42W8.
20. A method for producing nucleic acids, the method comprising isolating nucleic acids from the seed, plant, plant part, or plant cell of claim 11 .
