Molecular Markers Associated with Stem Canker Resistance in Soybean

摘要

The present invention provides methods and compositions for the identification and selection of loci modulating phenotypic expression of a stem canker resistance trait in plant breeding. In addition, methods are provided for screening germplasm entries for the performance and expression of this trait.

1. A method of identifying a soybean plant that comprises a genotype associated with an stem canker resistance phenotype, comprising:
(i) detecting in said soybean plant an allele in at least one stem canker resistance marker locus associated with the stem canker resistance phenotype wherein the stem canker resistance marker locus is in a linkage group D1b genomic region flanked by or including:
a) loci NGMAX008369670 and NGMAX008369689;b) loci NGMAX008369675 and loci NGMAX008369689;c) loci NGMAX008369673 and loci NGMAX008369689;d) loci NGMAX008369676 and loci NGMAX008369689;e) loci NGMAX008369683 and loci NGMAX008369689;f) loci NGMAX008369675 and loci NGMAX008369686;g) loci NGMAX008369673 and loci NGMAX008369686;h) loci NGMAX008369676 and loci NGMAX008369686; or,i) loci NGMAX008369683 and loci NGMAX008369686; and,(ii) denoting that said plant comprises a genotype associated with a stem canker resistance phenotype.
