Riau is one of the centers for pineapple production in Indonesia. Pineapple cultivated in Riau is a local variety that has been cultivated for generations for a long time. This study aims to examine the relationship and genetic diversity between local varieties cultivated in several districts on Riau peatlands based on RAPD (Random Amplified Polymorphic DNA) markers. Diversity analysis was carried out on ten local pineapple genotypes from five districts namely Kampar, Indragiri Hilir, Siak, Bengkalis and Dumai using 11 RAPD primers. The amplification of 11 RAPD primers tested on 10 pineapple genotypes resulted in 77 loci, with 73 polymorphic loci (96.42%). Based on the UPGMA dendrogram, the pineapple coefficient similarity in Riau Province ranges from 0.53 to 0.91. Based on the results of this study, it can be concluded that the relationship between pineapple genotypes in Riau Province ranges from 53 – 91%, which means that there is a diversity of 47 – 0.9%.
