SSR markers linked to meta-QTLs for white mold resistance in common bean

Abstract

Several studies have been conducted to identify QTLs for resistance to white mold in Phaseolus vulgaris. SSR markers have the advantages of being codominant and distributed throughout the genome, being considered one of the best genetic markers for mapping purposes and efficient to identify QTLs (Soule et al. 2011). In the meta-QTL analysis, SSR markers can be used to identify stable genomic regions in populations, and therefore, be more promising in marker-assisted selection programs. The objective of the study was to identify SSR markers nearby and/or within the meta-QTL intervals described by Vasconcellos et al. (2017), in order to evaluate the possibility of using these markers for resistance to Sclerotinia sclerotiorum in common bean.
