Banana is considered the most important fruit in Egypt. Many clones are grown for the export market, but many indigenous cultivars are produced and consumed locally. Bananas are affected by five viruses (Diekmann and Putter 1996) these are Banana bunchy top virus (BBTV) genus Nanavirus, Banana streak virus (BSV) genus Badnavirus, Cucumber mosaic virus (CMV) genus Cucumovirus, Banana bract mosaic virus (BBrMV) genus Potyvirus, and Banana mild mosaic virus (BanMMV),(Thomas et al., 2000; Gambley and Thomas 2001). Banana mosaic has been shown to be widespread in banana and also been noted in bananas from Africa, the Americas, Southeast Asia, and Australia (Lockhart and Jones 2000; Thomas et al., 2000). The occurrence of CMV has been reported in many hosts such as Egyptian henbane (Samad et al., 2000), gladiolus
