The aim of the present work was detection and identification of potato cyst nematodes (PCN) in two geographically distinct regions of Georgia – Samtskhe-Javakheti and Samegrelo – Zemo Svaneti. For this, 11 villages in Samtskhe-Javakheti and 9 villages in Samegrelo-ZemoSvaneti were studied. Two forms of cystic nematodes were found in the soil samples; Their morphological and morphometric studies werecarried out and identified species were confirmed by the multiplex PCR; Analysis of PCR products confirmed that PCN in 7 samples from Zemo Svaneti and in 2 samples from Samtskhe-Javakheti belongs to G.rostochiensi, identification of another form of PCN, Globoderaspp. remains the subject of farther research. Thus, PCN were found in two villages (Vale and Skhvilisi) of Samtskhe-Javakheti region, 5 villages (Ushxvanari, Lanchvali, Ifari, Tsvirimi, potato fields adjacent to the airport) of Samegrelo- ZemoSvaneti region.
