Electrophoretic analyses were effected in 2 populations of rubber trees (Hevea brasiliensis) for the enzymatic systems MDH, SKDH and LAP, with the objective of drawing inferences on the genetic structure of the populations. Four loci (LAP-1, LAP-2, SKDH and MDH-1), with 5, 4, 5, and 3 alleles/locus, respectively, were identified. The estimated variability parameters exhibit a high genetic variation for the 2 populations (HT = 0.3356) and the greater part of the variability is within the population (99.85 %). The parameters that measure genetic distance demonstrate that the 2 populations are similar. The results indicate that the collection of rubber tree germplasm in this region studied should be directed to 1 population, with a greater number of individual per population.
