Efficiency of Conversion of Virulent Strains to Hypovirulence in the Host and in the Laboratory

Efficiency of conversion is low en plain agar media unless strains paired are in the same, or closely related, vegetative compatibility groups. Efficiency is much better on the surface of cellophane over agar media. A single hypovirulent strain and 50 different normal. strains were paired on cellophane and in the host; 25 of the 50 vegetative compatibility types were converted at least once on cellophane, compared to 37 of 50 in trees.
