Abstract
The present invention relates to methods and compositions for identifying, selecting and/or producing a plant or germplasm having root increased drought tolerance and/or increased yield under non-drought conditions as compared to a control plant. A maize plant, part thereof and/or germplasm, including any progeny and/or seeds derived from a maize plant or germplasm identified, selected and/or produced by any of the methods of the present invention is also provided.
Claims20
A method of selecting a first maize plant or germplasm that displays either increased yield under drought or increased yield under non-drought conditions, the method comprising:
- a) isolating nucleic acids from the first maize plant or germplasm;
- b) detecting in the first maize plant or germplasm at least one allele of a quantitative trait locus that is associated with increased yield under drought, wherein said allele is located within 50 cM, 20 cM, 10 cM, 5 cM or 1 cM from any one of yield QTL 1-12;
- and
- c) selecting said first maize plant or germplasm, or selecting a progeny of said first maize plant or germplasm, comprising at least one allele associated with increased yield under drought.
A method introgressing a water optimization locus comprising:
- a) isolating a nucleic acid from a first population of maize plants;
- b) detecting in said nucleic acid the presence of at least one allele of a quantitative trait locus that is associated with increased yield under drought, wherein said allele is located within 50 cM, 20 cM, 10 cM, 5 cM or 1 cM from any one of yield QTL 1-12;
- c) selecting one or more plants with the water optimization locus from the first population of maize plants;
- and
- d) producing offspring from the one or more plants with the water optimization locus, wherein the offspring exhibit improved water optimization compared to the first population.
A plant having introduced into its genome a “water optimization gene” and or “yield allele”, wherein the said water optimization gene comprises a nucleotide sequence encoding at least one polypeptide comprising SEQ ID NO:
- 20-26 and the yield allele is any one as depicted in SEQ ID Nos:
- 1-12.
