Conteúdo: | Common bean cultivar Mexico 309 presents a wide resistance spectrum to several pathotypes of the fungus Uromyces appendiculatus that occurs in the states of Minas Gerais and Goiás, in Central Brazil. This pathogen is the causal agent of common bean rust. The present study had the following objectives: (i) to determine the inheritance of rust resistance in segregating populations obtained from crosses between cultivars Mexico 309 and Rudá (commercial cultivar susceptible to rust), and (ii) to validate the SCAR marker SI19460 as linked to 'Mexico 309' resistance gene. Results confirmed that 'Mexico 309' has a single dominant rust resistance gene (Ur-5) and that marker SI19460 is linked in coupling phase at 3.31 cM of this gene. This marker can be used for indirect selection of gene Ur-5 during the development of common bean lines resistant to rust using 'Rudá' as one of the progenitors.
