| Abstract: | A rapid and cost efficient technique was developed and used to generate 168 sequence tagged microsatellites (STMs) in the barley scald pathogen Rhynchosporium secalis. Sixty‐two STMs, amplifying 66 loci, revealed a high level of polymorphism among a diverse set of 16 Australian isolates. Each locus revealed two to nine alleles (average 4 ± 1.82), and a gene diversity measure of 0.54 was obtained. This technique not only halved the cost of marker development compared to traditional methods, but substantially reduced the cost of performing fluorescence‐based microsatellite assays. These STMs provide a powerful tool for genetic studies in R. secalis. |
