The wheat genetic diversity. (a) Schematic representation of the loss of natural genetic diversity through domestication and breeding in wheat. (b) Introduction of new genetic diversity through alien introgressions during wheat breeding. Percentage of wheat landraces (red), breeding material (green) and registered varieties (blue) as a function of the number of structural variations (OTVs: off‐target variants) observed with a 420K SNP array. The peaks centred on 2000 OTVs illustrate the creation of a new type of diversity based on alien introgressions.
