This dataset includes 2310 SNP loci of 79 isolates of the wheat stem rust fungus, Puccina graminis f .sp. tritici (Pgt). This data was used to assess the genetic diversity of a Pgt population (56 isolates) from Kazakhstan derived from stem rust samples collected in 2015-2017 wheat growing seasons. Twenty-three reference isolates from previously defined genetic clades were included in the analysis. Results indicate that the Pgt population form Kazakhstan is highly diverse and most of the isolates are of sexual origin. Data is being released now in conjunction with publication of a primary research paper that describes this work.

In the excel file, we provide the data of the 2310 loci from a custom Illumina SNP array (PgtSNP 3.0 K chip) used for genetic analysis.
