Ten isolates of cucumber mosaic virus (CMV) and two isolates of peanut stunt virus (PSV) were identified by host range, symptomatology, and serology. CMV isolates were divided into three groups according to host range and symptomatology and into two groups according to serological reactions. Comparisons with known cucumoviruses suggested that all Arkansas CMV isolates belong to the DTL serogroup and all Arkansas PSV isolates belong to the W serogroup.
