Abstract
The resistance of soybean trypsin inhibitor(STI) to the race 3 of soybean cyst nematode(Heterodera glycines Ichinohe,SCN)were studied by inoculating SCN to resistant varieties,Hartwig,Xiaoliheidou and susceptible cultivars,Liaodou 15,Zhonghuang 28.Results showed that the activity of STI with inoculation was higher than that without inoculation and the STI activity were also different among varieties.The dynamic trends of STI were varied with varieties.Results suggest that STI had attended the resistance of soybean to SCN and the resistant mechanism maybe different among soybeans.
