Abstract

Abstract: The cereal cyst nematode disease caused serious damage to the production of wheat in recent years.Accurate diagnosis is the basis for controlling this disease.37 cereal cyst nematode populations were extracted from different areas of Hebei province in this study.The morphological and molecular characters of the nematodes were systemically studied.The difference of ITS-rDNA sequences of all the tested nematode was small and these sequences are less than 1% differences between local populations and Heterodera avenae.The main morphological and morphometrical characteristics of different populations were studied.They were mostly close to H.avenae in morphology.We confirmed that the nematode populations that extracted from Hebei province are Heterodera avenae based on morphological,morphometrical and molecular characters.

Key words: Cerceal cyst nematode, Heterodera avenae, Morphological, ITS-rDNA
