摘要：

Isolates of Cryphonectria parasitica from chestnut trees in forest stands and commercial orchards were tested for virulence, distribution in vegetative compatibility (v-c) groups, and capacity of being converted to hypovirulence through acquisition of double-stranded RNA determinants from five hypovirulent isolates. Even though 77% of the virulent isolates were converted to hypovirulence, the low retrieval of hypovirulent isolates and the relatively high v-c diversity in our study area warrant further investigation.
