The high genetic variability of the pathogen and the occurrence of numerous physiological races complicate the development of varieties with durable resistance. The objectives of this study were to (i) characterize isolates of\n                    <jats:italic>C. lindemuthianum<\/jats:italic>\n                    collected from Zambia into physiological races and (ii) identify genomic regions associated with resistance to anthracnose in a recombinant inbred line (RIL) population. Four isolates collected from two major bean-producing districts of Zambia were characterized as races 7, 15, 17, and 291 using standard differential cultivars. A population of 110 F\n                    <jats:sub>5:6<\/jats:sub>\n                    RILs derived from a cross between Mwezi Moja, a Kenyan variety with purple speckled seed color, and Lusaka, a Zambian landrace with manteca yellow seed color, was evaluated for resistance to the four races and one uncharacterized isolate A23-13. RIL LM145 exhibited high resistance to all four races and the uncharacterized isolate A23-13.
