The interaction of beet western yellows virus (BWYV), lettuce mosaic virus (LMV) and cucumber mosaic virus (CMV) has been studied in lettuce cultivars Little Gem and Saladin. LMV infection alone or in combination with BWYV and or CMV caused the most severe symptoms and yield losses in both cultivars. BWYV caused more severe reactions in Little Gem than in Saladin; the reactions caused by CMV were mild in both cultivars. The interaction between BWYV and CMV infection resulted in a significantly greater yield loss in both cultivars than that caused by BWYV or CMV infection alone.
