Potato cyst nematodes(PCN), Globodera spp. are worldwide important pathogens and have become one of the main obstacles to potato production in Indonesia. Since the first detection of PCN in East Java in 2003, the nematodes have caused significant losses in three main potato production areas in Indonesia, Sumber Brantas, Kota Batu, in East Java (1,600-1,800 m above sea level) and Korang Tengah, Banjarnegara in Central Java (1,700 m above sea level). As the nematodes were newly introduce into Indonesia, little was known about their characteristics. To manage the parasite effectively it is very important to identify the species and the pathotype of the nematode populations. Morphometric observations and morphological characterization were conducted including the measurement of Granek's ratio for randomly sampled cysts, second stage juvenile(J2), females, males,and eggs. All specimens collected from above mentioned areas were identified as golden potato cyst nematode, Globodera rostochiensis.
