Abstract
We already reported four groups which contains some similar strains based on URP-PCR in the previous paper. The objective of this study was to confirm those strains by the amplified fragment length polymorphism (AFLP) and vegetative compatibility group (VCG). AFLP analysis showed no difference among these strains except ASI 2595 and 2183 in Weonhyeong group and ASI 2829 in Suhan group. They showed specific DNA bands only in the result of P + AG/M + AAG and P + GT/M + ATG primer combinations out of eight different combinations. The AFLP primers produced a total of 330 fragments between 80 and 1000 bp in length for 31 Pleurotus ostreatus strains. At a genetic similarity of 0.96, the UPGMA analysis separated the isolates into four distinct clusters. Each group was classified by similar strains. Confrontation test by vegetative compatibility groups (VCGs) also showed distinct line between strains from different groups, but no line between similar strains within the cluster. Our results indicate that most of similar strains was not distinctness. Thus, similar strains are considered to be very close on the genealogy of their parent or same strain with different name.
