Genome-wide association mapping of resistance to eyespot disease ( Pseudocercosporella herpotrichoides ) in European winter wheat ( Triticum aestivum L.) and fine-mapping of Pch1

Key message Genotypes with recombination events in the Triticum ventricosum introgression on chromosome 7D allowed to fine-map resistance gene Pch1, the main source of eyespot resistance in European winter wheat cultivars.
