A 1.8 kb fragment of 3' terminus of the viral RNA was amplified by RT PCR, cloned and its sequence was determined. Sequence comparisons showed that it shared 71.5%～99.1% homology with isolates of sugarcane mosaic virus, 67.8%～68.5% with sorghum mosaic virus and 38.4%～48.4% with maize dwarf mosaic virus, indicating that the pathogen of this disease on maize in Hangzhou was sugarcane mosaic virus.

Phylogenic analysis based on entire S1 gene sequences showed that majority isolates clustered together with the close phylogenetic relationships. Therefore, we researched pathogenicity of the selected isolate IBV CK/CH/LDL/05II in this group, Pathogenic study showed that this virus caused 100% morbidity and 54.5% mortality to 15-day-old specific-pathogen-free.The kidneys from the dead chickens showed the predominant gross lesions which were pale, mottled, and swollen. The renal tubules and ureters were distended with excess urates.
