Degenerate Potyviridae primers were used to amplify and sequence the 3′‐terminal regions of viruses from traditional and modern cultivars of sugarcane with mosaic disease growing in different areas of Yunnan province, China. Seven samples contained Sugarcane mosaic virus (SCMV), 11 contained Sorghum mosaic virus (SrMV) and two contained both viruses. SCMV was only isolated from traditional cultivars. In a phylogenetic analysis of the partial NIb and complete coat protein coding regions, most SCMV isolates formed a distinctive phylogenetic cluster (named SO) that otherwise contained only three Vietnamese isolates. SCMV variation seems mostly related to host genotype. In the same analysis, the SrMV isolates formed three major groups, one of which is reported for the first time, but the significance of the grouping is unclear.
