Abstract : The use of cultivars showing a good level of toleration or resistance, is a management practice to decrease the incidence of anthracnose in crops of mango. However, it is required to enlarge the test of cultivars to be able to offer new and larger options to the mango producers. This study was carried out at Caribia, a Research centre (C.I.) of Corporación Colombiana de Investigación Agropecuaria-Corpoica-, located in Sevilla (Ciénaga), departament of Magdalena, Colombia, during the first semesters of 1992, 1993 and 1994 (main harvest time in the Caribean Region). Eleven mango varieties were tested in 1992; fourteen in 1993; and fifteen in 1994, using a completely randomized design with three replications, taking three plants as experimental unit. The tested parameters, based on weekly lectures, were incidence and severity of the disease. The statistical analysis showed significant differences among treatments; the results suggest the cultivars Vandyke and Kent in 1992; Tommy Atkins, Keitt and Vandyke in 1993; and Tommy Atkins, Keiit, Early Gold, James Saigon and Vandyke in 1994 as the better options due to this low susceptibility to the anthracnose.
