The article provides information about phytonematodes found in potato soils and its root system in the Bulungur, Tailak, Samarkand, Pastdargom districts of the Samarkand region. During the study, 109 species of plant nematodes were discovered. According to the ecological classification, among devisaprobionts - 33 species and phytohelminths - 26 species (ectoparasites, endoparasites) predominate, pararisobionts - 20 species, mycohelminths - 23 species, eusaprobionts - 7 species. In the studied regions, plant nematodes of potato crops differed from each other in the diversity of species and the number of individuals. In the fauna of potato nematodes and soils around its roots, the Tailak (62 species) and Samarkand (59 species) regions dominated in terms of species diversity and number of individuals, while in the Bulungur (52 species) and Pastdargom (52 species) regions these species were relatively poorly represented. The Samarkand and Tailak regions have the greatest similarity between the faunal complexes of the potato nematode (0.67), the Samarkand and Pastdargom regions have the least similarity between the faunal complexes (0.58), while the similarity between the Bulgur and Pastdargom regions is the least (0.48). The fact that phytonematodes have slight differences in similarity coefficients between faunal complexes was explained due to the fact that they are formed in the same region both by soil type and climatic conditions. Among the plant nematodes found in potatoes, relatively common endoparasite species are Pratylenchus pratensis, Meloidogyne arenarai, Ditylenchus dipsaci which pose a threat to plants.
