Abstract
Occurrence and incidence of the single and multiple viral diseases in urdbean (Vigna mungo L.) caused by Mungbean yellow mosaic India virus(MYMIV), Groundnut bud necrosis virus (GBNV), Urdbean leaf crinkle virus complex (ULCD) were studied. Nine cultivars and 40 Initial Varietal Trial (IVT) lines of urdbean were sown in kharif and pre-kharif season of 2006 and 2007 at experimental farm at Indian Agriculture Research Institute, New Delhi. Varied degrees of incidence caused by single and multiple viruses’ infection were observed. Over all the study showed maximum disease incidence of 65.5-72.0% in urdbean cv. P 2056 by MYMIV, 66.1 % in cv. T 9 by ULCD, 14.5% in Pant U35 by GBNV, 21.5% in Barabanki Local by MYMIV+ULCD, 6.5% in T 9 by MYMIV+GBNV, 4.8% in Pant U35 by ULCD+GBNV and 3.0% in P 2056 by MYMIV+ULCD+GBNV. No cultivar of urdbean was found to be free from virus infection. Over all single and multiple infection was found to be less in pre-kharif compared to kharif season. The infection of specific virus was confirmed by biological reaction, insect transmission, electron microscopy (EM), DAC-ELISA and polymerase chain reaction (PCR)
