The first case of genetically modified and super high-yielding GM soybean in China is about to enter the field to produce soybeans, and the viral diseases that are about to enter the field produce a wide range of diseases that are difficult to prevent and control. Among the viruses that infect soybeans, soybean mosaic virus (SMV) causes the largest annual loss. Anti-SMV breeding of soybean, domestic and foreign traditional hybrid breeding methods have been for many years, little effect so far.
