This dataset includes 1838 SNP loci of 26 isolates of the wheat stem rust fungus, Puccina graminis f .sp. tritici. This data was used to assess the genetic relationship of a unique fungal isolate (18SPA092-1, race TKHBK) derived from a wheat stem rust sample collected in Spain in 2018 with a set of 25 reference isolates from previously defined genetic clades. Results indicate that isolate 18SPA092-1 had a unique multilocus genotype and constitutes a previously unknown lineage. 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 1838 loci from a custom Illumina SNP array (PgtSNP 3.0 K chip) after filtering loci with monomorphic and missing data.
