It was found by subsequent graft transmission to have a host range limited to only a few avocado cultivars. Extracts from CV-Ib–infected avocado were infective on Etrog citron and induced a slight leaf kinking and fruit deformation. The possibilities of extending viroid host ranges as a result of heterologous grafting among noncompatible hosts are discussed.
