First report of the occurrence of Wheat dwarf virus in wheat in China.
In May of 2004 and 2005, several diseased wheat (Triticum aestivum) plants showing extreme dwarfing, various types of yellowing, and reduced or no heading were found in breeding fields in Taiyuan, Shanxi Province, China. On the basis of these symptoms, infection with Wheat dwarf virus (WDV) was suspected. Analysis of DNA samples from diseased plants confirmed the identity of the pathogen. This is thought to be the first report of WDV in wheat in China.
