Pigeon pea is an important drought tolerant pulse crop. Yellow mosaic disease (PYMD) was appeared in the farmers’ field of Chhattisgarh. Present study aimed to record incidence & identify causal agent associated with PYMD and reason for low disease incidence. Survey and symptomatology was recorded in the farmers’ field of Chhattisgarh. PYMD incidence and vector population was recorded in the experimental field of ICAR-NIBSM, Raipur during summer 2017. Causal agent associated with PYMD was identified by PCR. Symptoms of PYMD was characterized as yellow mosaic, mottling, shortening of leaves and stunting, the disease incidence recorded in Chhattisgarh state was between 1.5 and 6.1 per cent and whitefly vector population was recorded as 1.8 to 3.2 per plant, causal agent associated with PYMD identified as begomovirus. Low incidence of PYMD in field, high vector population and positive PCR amplification by primers specific to begomovirus infecting tomato suggest that the begomovirus infecting tomato may be adapting to pigeon pea, a non-host species. This is the first report of the occurrence yellow mosaic disease in pigeon pea in the central India particularly in Chhattisgarh.
