title: Survey of sweetpotato viruses in China.
abstract: Ten sweetpotato viruses were surveyed in 3 major sweetpotato planting region (covering 11 provinces) in China from 2006 to 2010 to understand the distribution of sweetpotato viral diseases. Nine out of the 10 viruses were found in every major planting region. The most frequently detected virus in the Northern and the Yangtze River region was SPMSV. In the Southern region, SPVG was the most frequently detected virus. Compared to the results of the survey done in 1989, the incidences of all the viral diseases increased.
