Bread wheat (Triticum aestivum) is one of the world's most important crops; however, a low
level of genetic diversity within commercial breeding accessions can significantly limit
breeding potential. In contrast, wheat relatives exhibit considerable genetic variation and so
potentially provide a valuable source of novel alleles for use in breeding new cultivars.
Historically, gene flow between wheat and its relatives may have contributed novel alleles to
the bread wheat pangenome. To assess the contribution made by wheat relatives to genetic …
