Abstract: Sugarcane cultivation is hindered by several biotic constraints of which viral disease plays a major disaster. This study was carried out to evaluate the virus disease situation of sugarcane germplasm in western Cameroon, consisting of three regions (Southwest, Northwest and West region). A survey was carried out in 66 villages in these regions. Landraces identified included SMU58, SBK36, SNC16, NBfPc48 and NBfAg53. Representative samples of the landraces were collected and grown in an experimental field in the Department of Plant Science, University of Buea. Canes were observed for virus disease symptoms eleven months after planting. Single leaf samples of the symptomatic plants were collected from 10 randomly selected plants constituted a batch sample. A total of 66 and 15 batch samples collected from the field and experimental plot respectively were tested for the detection of Sugarcane Mosaic Virus (SCMV) and Maize Streak Virus (MSV) by direct Double Antibody Sandwich ELISA (DAS-ELISA). Of the 66 composite samples tested for SCMV and MSV, 54 samples tested positive for at least one virus. Maize streak virus was the most prevalent, with an incidence of 11.25%. Mixed infection was also recorded. Sugarcane in western Cameroon is infected with some virus diseases though the prevalence is low. This is a course of concern.
