Abstract

The rate of incidence of Potato virus Y (PVY), Potato virus X (PVX), Potato virus S (PVS), Potato virus M (PVM), Potato leafroll virus (PLRV) and Alfalfa mosaic virus (AMV) in potato fields of Khuzestan province was studied by ELISA, using 582 leaf samples collected in growing seasons of 1999 and 2000.
The results showed that one or more viruses infected 87 percent of samples. Among the viruses infecting potato, PVY with the incidence of 74% was the most common, followed by PVS, PVX, PLRV, PVM and AMV with the prevalence of 68, 44, 25, 22 and 11.5 percent, respectively.
Isolates of PVY, PVX and AMV were biologically purified and propagated in a suitable host. Based on the reaction of potato and indicator plants to 25 isolates of PVY and transmission tests with aphids (Myzus persicae), three strains of the PVY, namely PVY^O, PVY^N and PVY^C, were identified.
All seven PVX isolates were similar. Likewise, all AMV isolates were similar and belonged to Calico strain.
