SUMMARY A virus, now named peanut green mosaic virus (PGMV), was isolated from groundnut ( Arachis hypogaea ) in India and identified as a member of the potato virus Y group by electron microscopy, aphid transmission, and its chemical properties. It was sap transmissible to 16 species of the Leguminosae, Solanaceae, Chenopodiaceae, Aizoaceae and Pedaliaceae; Phaseolus vulgaris was a good local lesion host. PGMV remained infective in buffered groundnut leaf sap at dilutions of 10 ‐3 after 3 to 4 days at 25 °C, or heating for 10 min to 55 °C but not 60 °C. PGMV was transmitted in the non‐persistent manner by Aphis gossypii and Myzus persicae but was not seed‐borne. Purified virus preparations contained flexuous filamentous particles c. 750 nm long which sedimented as a single component with a sedimentation coefficient (S° 20w ) of 171S, and contained a single polypeptide (mol. wt 34 500 daltons) and one nucleic acid species (mol. wt 3.25 × 10 6 daltons). PGMV is serologically unrelated to peanut mottle virus (PMV) and other viruses infecting leguminous crops. Infected leaves contained cylindrical, cytoplasmic inclusions.
