Physico-chemical properties and biological pequliarities of soya mosaic virus strains in the Far East

The authors studied the strains diversity of soya mosaic virus in the Russian Far East. The biological and physico-chemical properties of 10 virus isolates, revealed on plants with different disease symptoms, were determined. It was shown, that all of investigated isolates belong to the light pathogenic (group A) and the middle pathogenic (groups B and C) strains.
