Dianthus spiculifolius Schur is an endemic and endangered plant species from Romania with high ornamental value. SSR markers were used to investigate the genetic structure of in situ populations of this species and also for study the genetic stability of in vitro plants. The molecular studies showed that the two populations are similar, and there are no specific markers of one population. The genetic variability of plants from natural habitats was conserved during in vitro culture. Genetic differences between somaclones derived from the same individual were low, so these plants can be used for ex situ collections and for ornamental purpose.

Key words: alleles frequency, gene diversity, heterozygosity, plant growth regulators, somaclonal variability, SSR markers
