Abstract

Fifty-three isolates of Armillaria gallica were collected in the Northeast of China.The genetic diversity of these isolates was revealed by ISSR analysis.Polymorphic bands were generated with 6 primers indicated that high diversity was conserved in the Chinese A.gallica isolates.The dendrogram of genetic relationships demonstrated that 3 isolates of China had generated distinct genetic differentiation.The other 50 isolates which were sampled from 3 different geographic populations were mixed into one cluster,and showed a closer genetic relationship without geographical isolation.
