Abstract
Cucumber mosaic virus (CMV) occurred widely in maize (Zea mays) and also rarely in teosinte (Euchlaena mexicana) in Kanto area, Japan. Isolates from maize plants were classified into two types (I and II) on their biological and serological properties. Isolate II, but not isolate I, infected to barley and wheat plants by sap inoculation. It suggested that the isolate I is closely to leguminous strain, but isolate II (tentatively named maize strain) may be a previously undescribed strain, on their host range and symptomatology. Isolates from teosinte plants appeared to be related to yellow (Y) strain on tabacco symptoms. We propose to designate teosinte necrotic mosaic for the disease.
