Abstract
Genetic structure of the mountain dwarf pine (Pinus mugo) and Scots pine (P. sylvestris) natural populations along with their 4 putative hybrid swarms in Slovakia were analyzed using 12 enzyme loci. The study aimed in evaluation of postulated hybrid status of the swarms on molecular level. Based on semidiagnostic allele frequencies of the MDH B, MDH C, 6PGDH B, ADH 1 and F-EST loci in their megagametophytes and vegetative buds, the conspicuous genetic differences were detected between P. mugo and P. sylvestris populations. The putative hybrid swarms seem to incline by their genetic structure to P. mugo rather than to P. sylvestris. Obtained results indicate independent developmental history of each of the scored hybrid swarms. The putative hybrid swarm in Suchá Hora was found to be a mixed stand consisting prevailingly of pure-species individuals of P. mugo and P. sylvestris. On the contrary, the putative hybrid swarms in Habovka, Tisovnica and Terchová are supposed to be of hybrid origin.
