The wheat cyst nematode disease is a kind of new disease in our County, in this summarize we will talk ahout living habit, configuration characteristic,harm, the fact influence hatch of the egg, dignose and control of this disease, so that we will realise and identify this disease more, and wiil establish a good basic for us to study more of this kind of disease.

Research progress on molecular diagnosis and resistance genes of the cereal cyst nematode,Heterodera avenae;

According to the sequence of Rccn4 which has high similarity to the nucleotide binding site(NBS) coding region of cereal cyst nematode Heterodera avenae resistance gene, Cre3, three 3 nested primers were designed.

Cereal cyst nematode (CCN) is a serious pest of cereal crops in many wheat growing regions of the world.

Specific primers were derived from the conserved motif of NBS sequence at the Cre3 locus, which conferred resistance to cereal cyst nematode (CNN) in the wild wheat ( Triticum tauschii ),and the specific primers were used in isolating a cereal cyst nematode resistance gene through a polymerase chain reaction (PCR) cloning approach.

According to the conversed sequences of NBS and LRR region of cereal cyst nematode resistance gene Cre3 from wild wheat (Triticum tauschlii) and the known NBS-LRR group resistance genes, two pairs of specific primers were designed for NBS and LRR region, respectively.
