Abstract

One hundred cowpea genotypes screened under field condition during kharif, 2013 and 2014 and further evaluated at greenhouse condition by artificial sap inoculation. The disease incidence varied from 0 to 60 % and 0 to 63.33 % in field and artificial condition respectively. The most of the genotypes studied were categorized as moderately resistant to moderately susceptible. Three out of hundred genotypes appeared to be immune (IC- 8966, V-5 and IC-202782) under both in field and artificial condition. The genotypes showed immune and resistant reaction would be utilized as donors to develop BCMV resistant varieties.
