Sugarcane (Saccharum spp.) is an important interspecific hybrid crop grown for sugar and ethanol production in tropical and subtropical regions around the world. However, its vegetative propagation makes it vulnerable to viral diseases which pose a serious threat to crop yield and quality. Several viruses belonging to species in the genus Mastrevirus, family Geminiviridae are known to infect sugarcane including maize streak virus, saccharum streak virus, sugarcane chlorotic streak virus, sugarcane streak Egypt virus, sugarcane streak Reunion virus, sugarcane streak virus, sugarcane striate virus and sugarcane white streak virus (SWSV), (Boukari et al., 2020).
