Allotetraploid wild emmer wheat, Triticum dicoccoides (TD) 2n¼28, the progenitor of most cultivated bread wheat, is an ecological specialist and excellent model organism for advancing evolutionary theory, wheat evolution, and wheat improvement. The center of origin and diversity of TD is northeastern Upper Galilee and the Golan. Elsewhere in the Fertile Crescent, it occurs in semi‐isolate…
Summary Climate change threatens reduced crop production and poses major challenges to food security. The breeding of climate-resilient crop varieties is increasingly urgent. Wild plant populations evolve to cope with changes in their environment due to the forces of natural selection. This adaptation may be followed over time in populations at the same site or explored by examining difference…
