The common bean cultivar Crioulo 159 provides a valuable source of resistance to Colletotrichum lindemuthianum (Sacc. & Magnus) Briosi Cavara. objective this study was characterize the genetic C. races 2, 64, 73, and 2047 through inheritance, allelism testing, molecular analysis. Populations were obtained from crosses between cultivars possessing anthracnose genes. Inheritance tests performed in F 2 population 2:3 families derived (R, resistant) × Cornell 49–242 (S, susceptible) inoculated with 73 showed segregation that fit ratios 3R:1S 1RR:2RS:1SS, respectively, indicating action dominant gene 159. absence recombination two identical sets race allowed conclusion single controls both races. Allelism revealed independence those previously characterized for Based on results, we propose naming newly discovered as Co‐16 . Molecular analyses sequence‐tagged site marker g2467 900/800 is linked coupling phase at 4.8 cM locus chromosome Pv04. Additionally, markers g2303, BARCPVSSR04561 BARCPVSSR04570, which are Co‐3 4 allele Ouro Negro, not
