Potato (Solanum tuberosum L.) is one of the most important crops grown for food in the world, but many potato-yield limiting biotic factors are present such as plant parasitic nematodes (PPN). This study was conducted to determine the nematodes associated with potato growing areas during 2014-2016 growing seasons in Bolu province. Overall, Root lesion nematode, Pratylenchus spp. were the most common nematode genus occurring in potato production fields with an incidence of over 52.5%. The Cyst nematode, Globodera spp. was found in 35% and Root knot nematode, Meloidogyne spp. was in 20% of the samples whereas potato cropping very frequently with low rotation, incidences of plant-parasitic nematodes were 62,5% of Ditylenchus spp., 50% Geocenamus spp., 40% for Helicotylenchus spp. or Rotylenchus spp., 30% for Paratylenchus and Amplimerlinus spp., 9% for Pratylenchoides spp. and Tylenchorhynchus spp. The survey results suggested that the presence and the abundance of plant-parasitic nematodes were found relatively high in potato growing areas in Bolu and may have a potential to cause dramatic yield losses. The comprehensive surveys are indispensable to define the distribution, frequency as well as more accurate identification of plant parasitic nematodes species, particularly Globodera spp., Meloidogyne spp. and Pratylenchus spp. species in potato growing areas of Bolu province.
