The objective of the present study was to characterize the genetic resistance of the Beija Flor cultivar by inheritance and to conduct allelism tests. The inheritance test was conducted in the F2 population derived from the Beija Flor (resistant) x TU (susceptible) cross inoculated with race 2047 of C. lindemuthianum. Furthermore, allelism tests exhibited a fitted segregation ratio of 15R:1S, thereby indicating the independence of the Beija Flor gene from the following previously characterized genes: Co-1, Co-2, Co-4, Co-42, Co-6, Co-12, Co-14, Co-15, and Co-Pe. Based on the aforementioned results, we are proposing the symbol Co-Bf to designate the new anthracnose resistance gene in the Brazilian Andean common bean cultivar Beija Flor. This cultivar is an important source of resistance to C. lindemuthianum that should provide a valuable contribution to the common bean breeding program for anthracnose resistance. 2021 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303067924006 https://www.redalyc.org/journal/3030/303067924006/ https://www.redalyc.org/journal/3030/303067924006/html/ https://www.redalyc.org/journal/3030/303067924006/303067924006.epub https://www.redalyc.org/journal/3030/303067924006/movil 10.4025/actasciagron.v43i1.44910 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
