Plants from a Nebraska wheat field were tested to determine the cause of mosaic symptoms. Electron microscopy of leaf-dip preparations showed thin, flexuous rods 12–15 nm in diameter and mostly 100–1,600 nm long. The virus was tentatively identified as wheat spindle streak mosaic virus on the basis of morphology, concentration of rods in leaf-dip preparations, morphology of inclusion bodies, pattern of occurrence in the field, and other factors. This is the first report of wheat spindle streak mosaic virus in Nebraska.
