During the spring and summer, in 2003-2004, pea viruses were identified in twenty pea fields of Tehran. Some leaf samples were collected randomly from pea fields of Tehran. Samples were tested by Double Antibody Sandwich Enzyme Linked Immunosorbent Assay (DAS-ELISA) technique using polyclonal antiserum of Alfalfa mosaic virus (AMV), AS-0001, DSMZ, Braunschweig, Germany). The samples were extracted in 0.1 M Phosphate buffer pH 7 to 7.5 and inoculated on Chenopodium amaranticolor, Chenopodium quina, Phaseolus valgaris, Vicia faba, Vignia unguiculata. Pea cultivars were infected by AMV, causing mild mosaic, translucent veins and a diffuse green-yellow of tender parts and spots may also was involved necrosis of tissue. Infected plants grow slowly and malformed pods produce fewer ovules. In Chenopodium amranticolor, C. quina chlorotic and necrotic flecks, and Vicia faba systemic mosaic had produced. Phaselous vulgaris and Viginia unguiculata are good assay hosts for strains that produce local lesions after 3-5 days in these plants. Back inoculated on Pisum sativum and Vicia faba and tested with DAS-ELISA that had been confirmed the results. This is the first report of AMV on pea from Iran.
