The rambutan is an exotic fruit that has a high market potential and the seedlings can be obtained by seed or vegetative. The production of seedlings by seed is routinely done in the state of São Paulo, having a high variability in the orchard, and take longer time to go into production. Although morphological characters are widely used in differentiation of the varieties, molecular techniques allow the comparison and identification of genetic material. Thus, the present research was realized, comparing rambutan stock plants and their progenies, by fAFLP. Analyses were realized at the Laboratory of Biochemistry of Microorganisms and Plants, Department of Technology - Faculdade de Ciências Agrárias e Veterinárias - UNESP - Jaboticabal/SP, using 06 plants of rambutan, denomined: A, B, C, D, E and F. Were collected leaves of 15 seedlings derived from each stock plant and was done the DNA extraction, being the samples quantified according to AFLP Plant Mapping Protocol (Applied Biosystems), using combinations of pairs primers: ACG / CAC, ACT / CAT, ACA / CTT and ACC / CTT. Can be concluded that the use of molecular markers is effective to distinguish the materials and to obtain the genetic distance; is not recommended to obtain seedlings by seed when the purpose is to install a commercial orchard.
