Evaluated the SMV resistance of 85 wild soybean and analyzed the con-elation of characters. The results showed that there were 5 resistant accessions, 14 moderately resistant accessions, 23 intermediate accessions, and 43 susceptible accessions, accounting for5.8% , 16.4% , 27.1% and 50.5% of the tested gennplasm, respectively. Correlation analysis for several characters and disease index of the accessions tested were conducted. There were a strong positive correlation between resistance to SMV and days from blossom to mature. The results indicated that the days from the blossom to the autumn among these characters played major role in determining resistance to SMV while the other characters were less related to the resistance. The cluster analysis indicated that accession Bian0526 had a far relationship with all other accessions, and had a hetero-sis when crossed with the other accessions.
