Description Serodiagnosis of symptomatic samples of sugarcane collected from number of sugarcane growing localities in Marathwada (Maharashtra), Andhra Pradesh (AP) and Tamil Nadu (TN) indicated that the sugarcane was predominantly infected by sorghum mosaic potyvirus-an immunity breaking strain (SrMV-IBS) in 39 localities out of 41 (95%) whereas mixed infections of sugarcane with SrMV-H was evident only in 5 localities (12%). Moreover, mixed infections of sugarcane with sugarcane mosaic potyvirus strains including SCMV-A (7%), SCMV-B (22%), SCMV-SC (7%) and with maize dwarf mosaic potyvirus-strain A (MDMV-A: 17%) were also evident in some localities. Infections of sugarcane by MDMV-A was detected only in Marathwada but not in AP and TN whereas infections of sugarcane by SrMV-H, SCMV-A, SCMV-B and SCMV-SC besides SrMV-IBS were found in Marathwada, AP and TN by SCMV-D, SCMV-E, infections of sugarcane varieties grown in Marathwada, AP and TN by SCMV-D, SCMV-E, SCMV-MDB and johnsongrass mosaic potyvirus (JGMV) were found to be totally absent in all the surveyed localities. Of these potyviruses detected in sugarcane, only three, SrMV-IBS (100%), SrMV-H (71%) and SCMV-B (14%) were mechanically transmitted from field infected sugarcane to glasshouse grown CK-60A, CS-3541 and Maldandi (M-35-1) sorghum genotypes
