The Symptoms Types in Soybean Leaves Caused by Soybean Mosaic Virus
We investigated the symptoms on 726 soybean varieties leaves inoculated by soybean mosaic virus (SMV) strains SC3 and SC7 to determine the different types and proportions of the symptoms on soybean leaves infected by SMV.SC3 systematic infected 643 out of 726 soybean varieties, among these, 313 showed mosaic and necrotic mixing symptoms, 272 showed mosaic and 57 showed necrosis.In the necrosis, there were 154 spots necrosis, 156 vein necrosis and 60 vein and spots necrotic mixing symptoms.SC7 systematic infected 607 out of 726 soybean varieties, among these, 359 showed mosaic and necrotic mixing symptoms, 203 showed mosaic and 45 showed necrosis.In the necrosis, there were 167 spots necrosis,152 vein necrosis, 79 vein and spots necrotic mixing symptoms and 15 dieback necrosis.The results showed that the primary symptom caused by SMV was mosaic and necrotic mixing symptoms, followed by mosaic, and the ratio of necrosis was the lowest;the necrotic symptoms usually showed as spots necrosis or vein necrosis, followed by vein and spots necrotic mixing symptoms, the ratio of dieback necrosis was the lowest.
