Genetic Diversity of

The tan spot disease of wheat caused byHere we used ISSR and RAPD markers to study the genetic diversity of 34The leaves having the typical symptoms of tan spot disease were collected and after fungal isolation, purification and identification, DNAs were extracted. After PCR amplification using each primer, PCR products were run in agarose gels, and the resulting bands were scored. Cluster analysis was performed using Un-Wighted Nighbor Joining method.A total of 178 reproducible bands were scored. Out of which 115 (65%) were polymorphic corresponding to an average of 8 polymorphic bands per primer. The average PIC values for ISSR and RAPD markers were 0.38 and 0.43, respectively. A high degree of genetic variability among IranianGenetic variability of
