Megjegyzések:	The ascomycete fungus, Cryphonectria parasitica (Murr.) Barr, is an important fungal pathogen of chestnut in Europe and North America. The pathogen kills the infected tree branches and the rapid death of the entire tree take place which is causing high environmental and economic concerns. In this study we employed a part of the translation elongation factor 1 subunit alpha (EF-1?=tef1) and ITS region, as a potential genetic markers to infer phylogenetic relationships among Cryphonectria parasitica isolates. The difference among the Cryphonectria parasitica isolates originated from the Carpathian-Basin was not insignificant because only six sites were considered as informative for the parsimony analysis. The bootstrap values were not enough high either to support real differences among isolates. Significant, well based differences were not found between Hungarian isolates. Little differences were found between Hungarian, Greek and isolates from database which constitute separate groups. It show also that the tef1 sequences could be suitable for studying C. parasitica isolates originated from geographical places far away from each other. As the differences among the different studied isolates were insignificant, we mean that the evolutionary distance by tef1 sequences within Cryphonectria parasitica isolates is too small to get well based consequences for the population diversity of this species.
