The influences of roots for different soybean cultivars on the hatching of cysts and the taxis of the second juveniles of Heterodera glycines

摘要

The soybean cyst nematode (Heterodera glycines, SCN) has become one of the most wide spread and destructive soybean pathogens in the world. China is the original regions of the soybeans. More than 300 million hectares of soybeans were infected by this pest. It is the best way using the resistant breeding to control the SCN in the world The resistant mechanisms for the resistant soybean cultivars were studied by many researchers.
