Genomic DNA prepared from fruitbdies of 25 Grifola frondosa strains were amplified with the ITS primers and the PCR reaction products were enzymed. The ITS bands have same electrophoresis patterns but part of them have different restriction enzyme cutting site. These strains were divided into three broad categories. SRAP amplification employing 47 SRAP primer pairs were carried on and 138 polymorphic bands were detected. The phylogram tree showed that: ten strains were differentiated from the others effectively and fifteen strains have no obvious differences between each other. The results implied that the ITS-RFLP and SRAP markers were effective methods for strains identifica tion and germplasm evaluation but other markers were also needed to be used in conjunction.
