摘　　要：Net blotch disease caused by the fungus Pyrenophora teres belongs to the complex of leaf blotch diseases that decrease the yield and the quality of barley （Hordeum vulgate L.）. This study deals with the use of microsatellites localized nearby the quantitative trait loci, associated with the resistance to P. teres to screen barley lines and varieties that could be introduced into a net blotch resistance breeding program. Thirty-five barley microsatellite loci and 65 barley genotypes, 265 alleles were detected. The number of alleles per locus ranged from 2 to 26. The arrangement of genotypes into clusters based on microsatellite data does not correspond to their resistance level to P. teres even though chosen microsatellite markers have been localized nearby QTLs associated with the resistance to P. teres.
