Abstract
A novel inbred maize line designated PHA9G and seed, plants and plant parts thereof. Methods for producing a maize plant that comprise crossing inbred maize line PHA9G with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PHA9G through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. Hybrid maize seed, plant or plant part produced by crossing the inbred line PHA9G or an introgressed trait conversion of PHA9G with another maize line. Inbred maize lines derived from inbred maize line PHA9G, methods for producing other inbred maize lines derived from inbred maize line PHA9G and the inbred maize lines and their parts derived by the use of those methods.
Claims17
A seed comprising at least one set of the chromosomes of maize inbred line PHA9G, representative seed of said line having been deposited under ATCC Accession Number PTA-6346, wherein said chromosomes comprise all of the alleles of inbred line PHA9G at the SSR loci listed in Table 2.
An F1 hybrid maize seed comprising an inbred maize plant cell of inbred maize line PHA9G, representative seed of said line having been deposited under ATCC Accession Number PTA-6346.
A process of introducing a desired trait into maize inbred line PHA9G comprising:
- (a) crossing PHA9G plants grown from PHA9G seed, representative seed of which has been deposited under ATCC Accession Number PTA-6346, with plants of another maize line that comprise a desired trait to produce F1 progeny plants, wherein the desired trait is selected from the group consisting of waxy starch, male sterility, herbicide resistance, insect resistance, bacterial disease resistance, fungal disease resistance, and viral disease resistance;
- (b) selecting F1 progeny plants that have the desired trait to produce selected F1 progeny plants;
- (c) crossing the selected progeny plants with the PHA9G plants to produce backcross progeny plants;
- (d) selecting for backcross progeny plants that have the desired trait and the alleles of inbred line PHA9G at the SSR loci listed in Table 2 to produce selected backcross progeny plants;
- and
- (e) repeating steps (c) and (d) to produce backcross progeny plants that comprise the desired trait and comprise at least 95% of the alleles of inbred line PHA9G at the SSR loci listed in Table 2.
A method of plant breeding comprising the steps of:
- (a) obtaining the molecular marker profile of maize inbred line PHA9G;
- (b) obtaining an F1 hybrid seed for which maize inbred line PHA9G is a parent;
- (c) inducing doubled haploidy of the F1 hybrid seed to create progeny without the occurrence of meiotic segregation;
- and
- (d) selecting progeny that retain the molecular marker profile of PHA9G.
A method for developing a maize plant in a maize plant breeding program comprising introducing a transgene conferring a trait into inbred variety PHA9G, wherein a representative sample of seed of variety PHA9G has been deposited under ATCC Accession No. PTA-6346.
