Differentiation of Sugarcane, Maize Dwarf, Johnsongrass, and Sorghum Mosaic Viruses Based on Reactions of Oat and Some Sorghum Cultivars

Abstract

(...) These viruses are separable based on symptom expression in sorghum and oat. JGMV, alone infects oat. Strains within MDMV and JGMV react uniformly in sorghum. SCMV strains differ in reactions on some sorghum cultivars. SrMV strains differ on two sorghum cultivars. These infectivity results clearly support the new taxonomy suggesting that, although helpful, it is not essential to have biochemical and serological laboratory capabilities to classify these 15 virus strains
