Morphometric and genetic analyses of the putative hybrid population Pinus sylvestris x P. mugo at the locality Medzi Borami, Slovakia, were made using morphometric traits of cones and needles, artificial hybridization between the respective species and restriction analysis of chloroplast DNA (cpDNA). A low degree of crossability between P. sylvestris and P. mugo was confirmed experimentally supporting the idea of a spontaneous hybridization between the species. According to the cone size and number of stomatal rows on ventral side of needles the putative hybrid population Medzi Borami occupied intermediate position between the neighbour population s of P. sylvestris and P. mugo. Restriction analysis of cpDNA revealed the prevalence of P. sylvestris haplotypes in the putative hybrid population.
