Popis: SUMMARY A virus has been isolated from celery crops in Lincolnshire, Cambridgeshire, and Norfolk, from eight different cultivars on 15 of 18 farms sampled, but has not been found in any cultivars on 10 farms in Lancashire. It has also been isolated from hemlock on three farms in Cambridgeshire. The incidence of infection has varied considerably with an average level of about 15 per cent but 90 per cent crop infections have been observed. The virus causes most prominent symptoms in cvs. Lathom Blanching and Fenlander, causing a slight stunting of the former and a more serious reduction in growth of the latter. It is aphid-transmitted in a non-persistent manner. The virus has flexuous rod-shaped particles approximately 780 nm in length, and is apparently restricted in its host range to the Umbelliferae. Its relationship to Western celery mosaic virus */*: */*: E/E: S/Ap is discussed.
