Conteúdo: | This paper intended to characterize the Pantaneiro horse, using RAPD markers. Blood samples were collected in five counties in Mato Grosso do Sul e Mato Grosso States. Arabian, Mangalarga Marchador and Thoroughbred were also included to estimate genetic distances and the existing variability among and within these breeds. From 146 primers, 13 were chosen for amplification and 44 polymorphic bands were generated. AMOVA indicated that the greatest portion of detected variability was due to differences among individuals within populations (75.47%). Analysis of the genetic variability among pairs of populations presented higher estimates for the five Pantaneiro populations with the Arabian breed, while lowest estimates were present by pairs formed among the Pantaneiro populations with the Mangalarga Marchador. Highest genic diversity was shown by the Pantaneiro (0.3396), which also showed highest genetic distance with the Arabuian and lowest with Mangalarga Marchador breed. UPGMA dendrogram showed distinct differences between naturalized (Pantaneiro and Mangalarga Marchador) and exotic (Arabian and Thoroughbred) breeds. Results suggest that the Pantaneiro presents a higher variability than the other studied breeds and has a close relationship with the Mangalarga Marchador. Individual Pantaneiro Horse populations showed distinctive grouping patterns and care should be taken with future crossbreeding programs to maintain diversity.
