The virus produces symptoms on sour cherry, primarily the variety Montmorency. Apricot, peach, and sweet cherry are symptomless hosts. Yellow mottling with irregularly shaped green islands or rings appear on the leaves of infected trees (A). A less common symptom is yellowing of the lateral veins, usually accompanied by a tip distortion (B). Fruit are misshapen with corky-brown, discolored pits, streaks or rings in the epidermis that extend into the flesh of the fruit. Infected fruit are bitter.
