Effect of Seed Borne Soybean Mosaic Virus Infection on Quality and Yield Parameters in Soybean

The seeds of soybean cultivars viz., MACS-450, JS-335, MACS-572, MACS-13,MAUS-2,MACS413 and MACS-158 were sown in experimental field during kharif 2006 and 2007. The observations of infection of SMV on seedlings, plant height, number of nodules/plant, 100 seed weight, seed germination and seedling vigour index were recorded. The results revealed that there was significant reduction in plant height, number of nodules/plant, 100 seed weight, seed germination (%) and seedling vigour index in virus infected plants of soybean varieties as compared to control.
