“…On the basis of host range, aphid transmission and presence of long flexuous rods in partially purified preparations, the isolates of this group were identified as WMV-2 (MONLAR and SCHMELZER 1964, VAN REGENMORTEL et al 1962, DEMSKI 1968, MILNE et al 1969. Isolates of the third group were identified as CMV on the basis of their wide host range, symptoms produced on diagnostic hosts, positive reaction with CMV antiserum and presence of polyhedral particles in partially purified preparations (PRICE 1940, MILNE et al 1969, TOMLINSON et al 1973).…”
