dc.descriptionCommon bean (Phaseolus vulgaris L.) is one of the most abundantly consumed legume crops as foods worldwide. In many African countries, this crop is an important staple food because of its rich nutrients. The Great Lakes region of Central Africa, which includes Rwanda, the nation with the highest per capita consumption of common beans worldwide, is known to be a center of common bean diversity in Africa. Increasing the amount of iron and zinc in common bean for biofortification has been a key breeding goal in Rwanda and other countries. In this study, using 192 accessions, including local landraces from Rwanda, breeding materials, released varieties, and others, we performed genome wide association studies (GWAS) to determine the loci governing those traits in addition to other agronomic traits. We identified a locus that was strongly associated with seed zinc concentration and candidate genes. The information might be a great help for marker-assisted breeding of this trait in common bean.
