Abstract

The objective of this work was to characterize the genetic diversity, using ISSR markers, of 70 genotypes of five species of Passiflora spp. in Boyacá, Colombia. For molecular characterization, samples of young leaves were collected from 11 municipalities of the Boyacá department. Genetic similarity was used to cluster the genotypes by the UPGMA method, and genetic structure was evaluated by the Bayesian model. Eight ISSR primers produced 138 loci. The formed cluster consists of two populations, with most individuals of the same species but from different geographic origins. The percentage of polymorphic loci is higher than 80%. The average value of heterozygosity is between 0.29 and 0.36 for population I and II, respectively, and the values of polymorphic information content are low. A moderate genetic differentiation (0.16) and high gene flow (3.35) are observed.
