The research result reports that the happening of stripe disease has a close relationship with the number and the rate of laodelphax striatellus.

Effects of rice-duck integrated farming on developing regularity of rice stripe disease;

In order to apply the molecular marker ST10 to marker-assisted breeding,which complete linkages with the rice stripe disease gene Stvb-i,47 rice materials were scanned with it.

The rice stripe disease has showed resurgence in middle and lower reaches of the Yangtze River of China since 2000, and it caused the greatest loss of rice production among all kinds of rice diseases in some parts of this region.
