【Abstract】 The resistance of 36 new soybean varieties(lines) from Jilin province to SMV were identified in 2003. Both methods of the artifical inoculation and the natural inducement in field were adopted.In the identifiction of artifical inoculation, 58.3% soybean varieties to the mixed strains of SMV were resistant; 30.6% soybean varieties to the strain of SMVⅠ, 30.6% to SMVⅡ and 41.7% to SMVⅢ were resistant. 94.4% soybean varieties were resistant in the identification of natural inducement in field. The four soybean varieties of gongjiao　97132-8,baijiao 9403-9,gongye 5056 and 9757-33 have higher level resistance to SMV in all the identification, and the gongjiao　97132-8 is the best.更多还原
