Abstract
A virus causing chlorosis of veins, mosaic, green banding along veins, and downward leaf rolling in sesame (Sesamum indicum) was isolated from sesame plants grown from seed imported from the Sudan. The virus was sap-transmissible to species of Amaranthaceae, Chenopodiaceae, Cucurbitaceae, Leguminosae, and Solanaceae. Chenopadium amaranticolor was used as a local lesion assay host and Pisum sativum cv. Little Marvel, as the propagation host for purification. The virus was nonpersistently transmitted by Aphis craccivora and Myzus persicae but was not transmitted through the seed of sesame. The virus remained infective in buffered leaf sap of Nicotiana benthamiaza at a dilution of 10 -5 after storage for 9 days at 25 C and heating for 10 min to 55 C (but not to 60 C)
