Abstract:

An Indian isolate of Cowpea mosaic virus (CpMV) was found easily transmitted under glass house conditions by mechanical sap inoculation, using 0.1% potassium phosphate buffer (pH 7.4). Symptoms of mechanical transmission were characterized by mosaic, veinal necrosis, vein clearing, vein banding, blistering, stunting, leaf deformations, chlorosis and cupping of leaves. Three Aphid species viz. Myzus persaicae, Aphis Gossypii, and Aphis craccivora were found successfully transmitted the Cpmv from plant to plant. Acquisition feeding period of 40-60 seconds was found enough to acquire virus with maximum transmission of 73.3% by Myzus persicae. The virus was also found to be transmitted by seed and noticed high disease incidence (37.1%) with seeds collected from mechanically inoculated plants, than seeds collected from healthy seed lot (18.5%). Thus the virus under study was seed borne and sap transmissible, and it was also transmitted by Aphid vector in a non-persistent manner.
