Hybrids Infected by Maize Dwarf Mosaic Virus, Sugarcane Mosaic Strain MDMV-B, and Johnsongrass Mosaic Virus Click on the image above to download a complete copy of this publication in PDF format.

Hybrids expressing the red-leaf symptom show greater reduction in yield.
Therefore, inoculation of sorghum hybrids with these viruses will identify those having only the mosaic reaction and, thus, less yield loss and also may indicate which viruses are causing the symptoms. This text was extracted from the publication, SRL121.
