Soybean mosaic virus (SoyMV) infection caused reduction in the growth and yield of soybean plants. Plant height was reduced from 4.04 to 16.9 percent. Total number of pods per plant were reduced from 8.4 to 33.4 percent. Infected plants produced shortened and flattened pods with a reduction in pod length from 10.0 to 25.6 percent. Pods formed on the diseased plants had one or two grains and the reduction in the number of grains per pod was recorded from 6.4 to 15.2 percent. Loss in weight of seeds from diseased plants ranged from 6.6 to 17.8 percent.
