THE CEREAL CYST NEMATODE HETERODERA FILIPJEVI (MADZHIDOV) IN TURKEY

Abstract

In Central Anatolia cyst nematodes were found in 41.1% of the cereal fields surveyed. Three species belonging to the Heterodera avenae group were differentiated. At tow sites H. latipons was present and at one site a species which may be identical to H. avenae (s. str.). The majority of records (25) belonged to a third species close to H. avenae. Based on electrophoretic studies and morphological characters of cysts and secondstage juveniles this species was identified as H. filipjevi (Madzhidov, 1981), of which populations from the former USSR were available for comparison.
