Survey, symptomatology, transmission, host range and characterization of begomovirus associated with yellow mosaic disease of ridge gourd in southern India.

ABSTRACT: Ridge gourd is an important vegetable crop and is affected by several biotic and abiotic factors. Among the different biotic factors, ridge gourd yellow mosaic disease (RgYMD) is new emerging threat for the production of ridge gourd. The incidence of the RgYMD varied from 30 to 100% in southern India with highest disease incidence of 100% observed in Belagavi district of Karnataka state. The infected plants showed chlorosis, mosaic, cupping of leaves, blistering, reduction in leaf size and stunted growth. The varieties/hybrids grown in the farmer's fields were found to be susceptible to the disease. Begomovirus was detected in 61 out 64 samples collected from different areas of southern India.
