Through molecular studies, the genetic distance among 12 genotypes of A. comosus for RAPD markers (Random Amplified Polymorphic DNA) was determined using 11 primers (decamers) of the OPERON Technologies Inc. From the 12 genotypes, 1 came from Jamaica, 2 from the State of Acre (Quinari and RBR-1), 2 from the State of Maranhão (Turiaçu and São Domigos), 3 the State of Piauí (Cefas, Floriano-1 and Floriano-2), 2 from the State of Bahia (Monte Alegre-1 and Monte Alegre-2) and 2 from Minas Gerais (Pérola and Smooth Cayenne). By the analysis of cluster, using the method of UPGMA, a great divergence was verified among the genotypes of A. comosus studied or tima separation in two groups of a genetic distance of 31,1%.
