The aim of this work was to evaluate the resistance to rust in coffee carrying S H3 gene and other S H genes. Twenty one CIFC’s coffee trees with several resistance genes S H were evaluated in field conditions. All the evaluated coffees carrying Sh3 gene presented resistance to the rust. It was possible that rust races with the virulence gene v3 in the Paraná State didn’t exist. The S H3 gene in combination with genes S H5, S H6, S H7, S H8, S H9 and S H? would be very important to obtain cultivars with more durable resistance to the rust. O objetivo deste trabalho foi avaliar a resistência à ferrugem em cafeeiros portadores do gene S H3 e outros genes S H em Londrina, Paraná, Brasil. Foram avaliados vinte e um cafeeiros do CIFC com diferentes genes S H de resistência em condição de alta incidência natural em campo. Todos os cafeeiros avaliados portadores do gene S H3 apresentaram resistência à ferrugem. É possível que não existam raças de ferrugem com o gene de virulência v3 no Paraná. Plantas portadoras do gene S H3 em combinação com os genes S H5, S H6, S H7, S H8, S H9 e S H? seria muito importante para obter cultivares com resistência mais durável à ferrugem
