A review of the literature discloses a number of cucumber-mosaic viruses infecting celery. Doolittle and Wellman (1934)3 described the symptoms of southern celery mosaic in Florida. (Wellman (1934)) considers the virus causing the disease a new one. He reached this decision when a comparative study of southern celery-mosaic virus and common cucumber-mosaic virus disclosed a difference in certain physical properties and in symptoms produced on differential host plants. Wellman gives southern celery mosaic the designation “celery virus 1.” He does state, however, that “It is believed upon careful study of symptoms described in reports of celery mosaics by (Poole (1922)), (Elmer (1925)), and (Harvey (1925)), that these investigators were working with common cucumber mosaic (Cucumber virus 1, Doolittle).”
(Price (1935)), after a comparison of southern celery-mosaic and common cucumber-mosaic viruses, came to the conclusion that the two viruses are closely related immunologically, and, it is believed, should be classified as strains of the same virus.
(Smith (1937)) reported southern celery-mosaic virus to be synonymous with common cucumber-mosaic virus. It would seem, therefore, that (Smith (1937)) would have been more accurate in classifying (Wellman’s (1934)) southern celery-mosaic virus as a strain of common cucumber mosaic rather than as the same virus. (Smith (1937)) classified (Doolittle’s (1920)) cucumbermosaic virus as “Cucumis virus 1,” adding this name to the names already applied to the virus.
(Holmes (1939)) classified common cucumber-mosaic virus as cucumbermosaic virus, typical strain, Marmor cucumeris var. vulgare.
Field investigations were undertaken in the Salinas Valley by the author to determine whether this strain of common cucumber-mosaic virus had established itself on celery transplanted from Florida and grown in the valley.
