Abstract

IGS-RFLP markers were used to determine the genetic structure of Syrian field populations of the barley leaf stripe pathogen Pyrenophora graminea. Genetic variation was high in Syrian populations of P. graminea. A total of 366 scorable DNA bands were obtained, and 290 of these (79.2%) were polymorphic. Genetic distances among all isolates ranged from 0.01 to 0.74 with a mean of 0.29. The described IGS-RFLP analysis appears to be a useful tool to study genetic variation within P. graminea populations.
