In this study, the in vitro and in vivo essential oil ( EO ) composition and genetic variability in six micropropagated genotypes of Thymus saturejoides Coss ., a Mediterranean medicinal and aromatic plant, were analyzed by GC / MS and randomly amplified polymorphic DNA ( RAPD ). Yield and composition of the EO varied between genotypes. Cluster analysis based on RAPD data and EO grouped the six genotypes in three groups in both culture conditions, thus showing considerable intraspecific genetic and chemical variations. Applying the Mantel test, the result showed a significant correlation between the two proximity matrices RAPD and EO obtained from in vitro genotypes, whereas this correlation was not observed when using the EO obtained from the in vivo genotypes.
