Investigation of the Resistance Characteristics of the Soybean from Various Resources to the SMV-inoculated N3 and SC-7 Germplasm

108 lines of wild soybean populations from Shandong and Shanghai and 83 cultivars from some other provinces in China have been identified for their resistance to SMV-inoculated N3 and SC-7 germplasm.In addition,32 lines of perennial wild soybean were used to investigate its resistance to SMV-inoculated strain N3.The results showed that the resistance of Shandong wild population to SMV was significantly higher than that of Shanghai population.4 lines with high resistance to the SMV-inoculated strain N3 and 5 lines with high resistance to the SMV-inoculated SC-7 were selected from Shandong population.Furthermore,13 cultivars with high resistance to SMV-inoculated N3 and 10 cultivars with high resistance to SMV-inoculated SC-7 was obtained respectively from the cultivated soybean,and 1 line with high resistance to SMV-inoculated N3 was selected in perennial wild soybean.
