Abstract

This study was conducted during 2007-2008 to determine the genera/species of plant parasitic nematodes associated with wheat in cold regions of the Kohgiluyeh and Boyer-Ahmad province of Iran. Plant parasitic nematode population densities were determined in 100 soil and root samples collected from 21 cereal growing districts of the province. Seven genera of plantparasitic nematodes, including Pratylenchus , Helicotylenchus , Heterodera , Tylenchorhynchus , Xiphinema and Ditylenchus were found associated with cereal crops. The most important damaging plant-parasitic nematodes detected, were Pratylenchus (16.8%) and Helicotylenchus (14.8%). Their population densities per 50g of root were above damaging levels in some of the cereal fields surveyed.
