摘要

Thirty-four popular soybean cultivars were evaluated in experimental fields of ICAR-Indian Agricultural Research Institute (IARI), New Delhi during the Kharif / Rainy season to determine the association of viruses with mosaic and mottle diseases. Prominent symptoms observed in these cultivars were mosaic, mottle, puckering, stunting and leaf rolling. DAC-ELISA, PCR and RT-PCR analysis of symptomatic leaves showed the mixed infection of five viruses i.e., bean pod mottle virus, cowpea mild mottle virus, mungbean yellow mosaic India virus, soybean mosaic virus and soybean yellow mottle mosaic virus in these cultivars. The most prevalent virus was soybean yellow mottle mosaic virus with higher absorbance values in 33 cultivars, followed by soybean mosaic virus in 20 cultivars. Mixed infection of five viruses was observed in eight cultivars (JS-335, JS-2029, JS-2034, JS-2098, JS-20-116, Monetta and MACS-13 and SL-979) and four viruses in thirteen cultivars, whereas other cultivars were infected with one to three viruses in various combinations. Our study described the report of bean pod mottle virus infecting soybean on serological basis. Multiple viral infections can exacerbate symptoms and potentially affect yield and quality. Therefore, this study highlights the need to monitor and address multiple viral infections simultaneously and to develop effective management strategies against these viruses in soybean.
