Abstract: Soybean plants, germplasm and seed comprising at least one native locus conferring improved stem canker tolerance, molecular markers useful for identifying and, optionally, selecting soybean plants displaying tolerance, improved tolerance, or susceptibility to stem canker, and methods of their use are provided. Also provided are isolated polynucleotides, probes, kits, systems, and the like, useful for carrying out the methods described herein.

Abstract: This invention relates to molecular markers useful for identifying and, optionally, selecting soybean plants displaying tolerance, improved tolerance, or susceptibility to root-knot nematode, methods of their use, and compositions having one or more marker loci. In certain examples, the method comprises detecting at least one marker locus. In other examples, the method comprises detecting a haplotype comprising two or more marker loci. In further examples, the method further comprises crossing a selected soybean plant with a second soybean plant. This invention further relates to primers, probes, kits, systems, etc., useful for carrying out the methods described herein.
