A detailed study of a virus isolated from potato has been made. The virus isolate was both sap transmissible and transmissible by Myzus persicae Sulz. which was found to be a very effective vector. Typical symptoms of the diseases were produced within 11 to 12 days of inoculation. Various symptoms produced on chilli and potato variety are described. The virus had a thermal inactivation point of 55-60° C., a dilution end point of 1: 500-1:750 and a longevity of two days at room temperature in vitro. The virus was tentatively identified as Potato virus Y.
