Key message Identification of Rk candidate gene and diagnostic markers enabled precise introduction of the slow‑darkening (SD) allele into pink beans, producing stable SD phenotypes and expanding breeding utility across market classes. Abstract Common bean ( Phaseolus vulgaris L.) is a globally important and nutritious crop with diverse market classes. Multiple genes control the seed coat color and patterns that characterize t...

The Middle American rust resistance gene Ur-11 present in common bean ( Phaseolus vulgaris L.) confers resistance to all but one known race of the pathogen Uromyces appendiculatus (Pers.) Unger. Even though progress has been made in understanding the host–pathogen interactions between common bean and U. appendiculatus , the causal alleles of the majority of rust resistance loci, including Ur-11, remain unknown. A genome-wide a...
