Molecular markers linked to PPO inhibitor tolerance in soybeans

摘要

This invention relates generally to the detection of genetic differences among soybeans. More particularly, the invention relates to soybean quantitative trait loci (QTL) for tolerance to protoporphyrinogen oxidase inhibitors, to soybean plants possessing these QTLs, which map to a novel chromosomal region, and to genetic markers that are indicative of phenotypes associated with protoporphyrinogen oxidase inhibitor tolerance. Methods and compositions for use of these markers in genotyping of soybean and selection are also disclosed.

主权项

1. A method of selecting a soybean plant or germplasm with tolerance or improved tolerance to herbicides that inhibit protoporphyrinogen oxidase function, the method comprising:
a) isolating nucleic acid from a soybean plant or germplasm, wherein said isolated nucleic acid comprises at least one allele of a marker locus that is associated with the tolerance or improved tolerance to herbicides that inhibit protoporphyrinogen oxidase function, wherein the marker locus is localized within a chromosome interval flanked by and including S08102-1-Q1 and S08101-3-Q1 on linkage group L; and b) selecting the soybean plant or germplasm comprising the allele, thereby selecting a soybean plant with tolerance or improved tolerance to herbicides that inhibit protoporphyrinogen oxidase function.
