Association mapping of a locus that confers southern stem canker resistance in soybean and SNP marker development.

ABSTRACT: BACKGROUND:Southern stem canker (SSC), caused by Diaporthe aspalathi (E. Jansen, Castl. & Crous), is an important soybean disease that has been responsible for severe losses in the past. The main strategy for controlling this fungus involves the introgression of resistance genes. Thus far, five main loci have been associated with resistance to SSC. However, there is a lack of information about useful allelic variation at these loci. In this work, a genome-wide association study (GWAS) was performed to identify allelic variation associated with resistance against Diaporthe aspalathi and to provide molecular markers that will be useful in breeding programs. RESULTS:We characterized the response to SSC infection in a panel of 295 accessions from different regions of the world, including impor
