Random amplified polymorphic DNA (RAPD) markers were used to determine genetic relationships among five native populations of Liquidambar orientalis Mill. Eighty-four oligonucleotide primers were used in PCR and 782 RAPD markers were evaluated for statistical analysis. Generated Nei-Li’s coefficient indicated that the highest similarity was 83.1% between samples from Koycegiz and Cine populations, while the lowest as 68.3% between samples from Gunluklu and Karacaoren populations.

Key words: Liquidambar orientalis, RAPD analysis, similarity, sweet gum.
