Identification of a strain of maize dwarf virus infecting sorghum in Venezuela


, : Identification of a strain of maize dwarf virus infecting sorghum in Venezuela. Interciencia 21(3): 166-170

A sorghum virus isolated from an experimental crop at Maracay, Aragua State, Venezuela, was mechanically inoculated into differential hosts for identification. The virus infected sorghum (Sorghum bicolor), maize (Zea mays) and johnsongrass (Sorghum halepense) but not oats (Avena sativa), barley (Hordeum vulgare), wheat (Triticum aestivum) or sugarcane (Saccharum officinarum) cv CP-31294 and CP-31588.
