The natural occurrence of white clover mosaic virus in sweet pea (Lathyrus odoratus) in south‐east England

Abstract

White clover mosaic virus was isolated from glasshouse‐grown sweet pea plants with conspicuous flower ‘break’ symptoms. Plant growth was severely affected. The virus was transmissible by sap inoculation to sweet pea and other leguminous species. It was found naturally in Trifolium repens growing nearby. No natural vector is known.
