Abstract: The objective was to identify spontaneous hybrids between P. mugo and P. sylvestris using organelle DNA markers in sympatric zones at the sea-side spit of Kursiu Nerija in western Lithuania. A field inventory was carried out over the entire Lithuanian part of the spit and 203 individuals morphologically intermediate between P. sylvestris and P. mugo were tested for their male parent with chloroplast DNA PCR-RFLP markers and for their female parent with mitochondrial DNA PCR markers. Unfortunately, the mitochondrial DNA Nad7 marker failed to identify the female parent species in our study. However, the chloroplast DNA PCR-RFLP marker revealed that out of 203 tested individuals only 23 had a paternity different than that indicated by morphology. Of these, 13 individuals were morphologically identified as P. sylvestris but possessed cpDNA of P. mugo (putative hybrids with P. sylvestris (female) xP. mugo (male parent), and 10 individuals morphologically identified as P. mugo possessed cpDNA of P. sylvestris and may be hybrids with P. mugo (female) xP. sylvestris (male parent). The remainder of the 177 individuals identified in the field inventory were were considered as pure species. In conclusion, our study indicates ongoing spontaneous hybridization between P. mugo and P. syvestris in Kursiu Nerija. Human impact via seed transfer on altered hybridization rates as well as evolutionary consequences are discussed
