Head smut is one of the most devastating diseases in maize， causing severe yield loss worldwide. The present invention describes the fine-mapping of a major QTL conferring resistance to head smut. Markers useful for breeding， and methods for conferring head smut resistance are described. Nucleic acid sequence from the genetic locus conferring head smut resistance is disclosed. Genes encoding proteins conferring head smut resistance are disclosed. Head smut is one of the most devastating diseases in maize， causing severe yield loss worldwide.
