Distribution and Frequency of Vegetative Compatibility Types of Virulent Endothia parasitica Strains Near Parsons, West Virginia

The distribution and frequency of vegetative compatibility types of virulent isolates to Endothia parasitica were examined over a 3-year period from 1977 to 1979. Isolates were obtained from cankers on American chestnut stems found in two areas near Parsons, West Virginia. After pure cultures of Endothia parasitica were obtained from each canker, the compatibility type was determined by pairing mycelial plugs on amended potato dextrose agar. For the 3 years combined, a total of 449 isolates have been examined and 324 (72 percent) have been classified into 16 vegetative compatibility groups.
