{"Label"=>"UNLABELLED"} European winter wheat cultivar "Tabasco" was reported to have resistance to powdery mildew disease caused by {"i"=>"Blumeria graminis"} f. sp. {"i"=>"tritici"} ( {"i"=>"Bgt"} ) in China. In previous studies, Tabasco was reported to have the resistance gene designated as {"i"=>"Pm48"} on the short arm of chromosome 5D when a mapping population was phenotyped with pathogen isolate {"i"=>"Bgt19"} collected in China and was genotyped with simple sequence repeat (SSR) markers. In this study, single-nucleotide polymorphism (SNP) chips were used to rapidly determine the resistance gene by mapping a new F {"sub"=>"2"} population that was developed from Tabasco and a susceptible cultivar "Ningmaizi119" and inoculated with pathogen isolate NCF-D-1-1 that was collected in the USA. The segregation of resistance in the population was found to link with {"i"=>"Pm2"} which was identified in Tabasco. Therefore, it was concluded that the previously reported {"i"=>"Pm48"} on chromosome arm 5DS in Tabasco should be the {"i"=>"Pm2"} gene on the same chromosome. The {"i"=>"Pm2"} was also found in European cultivars "Mattis" and "Claire" but not in any of the accessions from diploid wheat {"i"=>"Aegilops tauschii"} or modern cultivars such as "Gallagher," "Smith's Gold," and "OK Corral" being used in the Great Plains in the USA. A KASP marker was developed to track the resistance allele {"i"=>"Pm2"} in wheat breeding. {"Label"=>"SUPPLEMENTARY INFORMATION", "NlmCategory"=>"UNASSIGNED"} The online version contains supplementary material available at 10.1007/s11032-023-01402-3.
