【 摘 要 】

The objective of this study was to characterize the genetic diversity within a Passiflora collection by PCR-RAPD markers. Genetic analysis was performed in 70 accessions, representing 11 species of the genus Passiflora. The use of only five primers produced 136 reproducible polymorphic bands. The hierarchical classification showed high levels of dissimilarities between and within the species studied. A clear separation was obtained among species and accessions of P. edulis and P. edulis f. flavicarpa, which were forms of the high commercial value species. The fingerprints produced from the studied genotypes would allow the identification of improved varieties/populations in an easy, fast and inexpensive manner.
