Abstract:
:This study characterized the genetic diversity of four populations of Ilex paraguariensis, a plant species native to South America, using random amplified polymorphic DNA (RAPD) markers. A total of 341 different RAPD bands were generated by the 15 primers analysed. High genetic variability was detected within each population, with an average diversity of 0.163. The within-population variation was large, probably as a result of the life history characteristics of I. paraguariensis. The average distance between individuals from each population was 0.392 and that between populations was 0.433, indicating a low between-population divergence. Most bands were common to all populations and the population-specific bands occurred at low frequencies. Partitioning of the genetic diversity indicated that 85% of the variation occurred within populations and only 15% between populations. Although most of the variability is within populations, clusterings of plants in each population were observed in the dendrogram.
