A widespread disease of groundnut (peanut), reported for the first time in the Sudan, was induced by a virulent strain of peanut mottle virus. The virus was identified on the basis of particle morphology, host range and reaction, serology, insect transmission, and physical properties. The isolate was not related serologically to three viruses in the potyvirus group. No resistance was found in 16 cultivars of groundnut tested in the field.
