Abstract: 

This study was carried out to determine the presence of Eggplant mottled dwarf virus (EMDV) and its natural host range in Northern and Razavi Khorasan provinces between June 2003 to September of 2004. For this purpose plants showing, leaf malformation, dwarfing and vein clearing symptoms were collected from different cultivars of solanaceae and cucurbitaceae, from areas such as: Mashhad, Neishabour, Torbate-Jam, Jim-Abad, Fariman, Sarakhs, Chenaran, Ghochan and Bojnord. Each sample was individually prepared for serological tests including ELISA and double diffusion in agar, using special antiserum of the virus. The efficiency mechanical transmission and host range studies were preformed on 16 different plant species under controlled environmental condition in a greenhouse. The results showed that Northern and Razavi Khorasan provinces were both infected with Eggplant mottled dwarf virus. In Northern Khorasan the natural host range of this virus was only limited to eggplant whereas in Razavi Khorasan, in addition to eggplant, potato and tomato were also infected. In this state, Neishabour had the highest infection rate while there was no infection in Sarakhs and Torbatejam. The results of double diffusion test for isolates from different regions and hosts reveled the existence of just one active virus serotype in Northern and Razavi Khorasan provinces.
