Abstract

In this paper, the Croatian sibirea (Sibiraea
croatica Degen), a rare and endemic species of the
Croatian and Bosnian-Herzegovinian flora, as well
as their tertiary relict, was compared with Altaic
sibirea (S. altaiensis (Laxm.) C. K. Schneider). For
the research, all samples of sibirea were collected
from four locations, one in Bosnia and Herzegovina,
one in Croatia and two in Russia. Their genetic
structure, genetic diversity, genetic differentiation
of the population and their genetic characteristics
were analyzed as well as the relationship of the
population of Sibiraea croatica Deg. which grows
in the regions of Croatia and Bosnia-Herzegovina
as opposed to Altaic sibirea (S. altaiensis (Laxm.) C. K. Schneider), from Southern Russia (plantation)
and Southern Siberia. During the DNA analysis,
16 primers were used, which were combined
at amplification. On the basis of molecular analyses
of regions in genomic and chloroplast DNA,
their genetic closeness was determined. Therefore,
the authors suggest that the Croatian sibirea (Sibiraea
croatica Deg.) is not a separate species, but
should be recognized at a lower taxonomic rank
as the ecotype of the Altaic sibirea (S. altaiensis
(Laxm.) C.K. Schneider). Based on the phylogenetic
analysis of internal transcribed spacer (ITS)
regions in genomic ribosomal genes (rDNA), the
phylogenetic position of Sibiraea spp. was confirmed
within the Rosaceae family.
