In the article of Vejl et al., (2002) it was shown that G. pallida amplified 239 bp fragments for the Kalle, Chavornai and Delmsen populations and G. rostochiensis obtained 411 bp amplimers for Šluknov and Harmerz, and 274 bp amplimers for the Obersteinbach population. As we obtained two 274 bp products for both the Ponikve and Milatovići populations, this could indicate a possible genetic similarity of the two Serbian populations to the German one. This hypothesis can be resolved by nucleotide sequencing, which will be the subject of further investigations.
