Both emmer and durum wheats are tetraploids with genome designation AABB. Because the initial product of fertilization between the tetraploid and diploid species is inviable after a few weeks, an embryo rescue procedure must be used in many cases.

Theor Appl Genet 108:261273, Johnson BL (1975) Identification of the apparent B-genome donor of wheat. Evolving from an ancestral plant called emmer that still exists today, domestication of wheat was at least 12,000 years ago. Dr. Patrick Byrne shows research plots of different D-genome wheat accessions that were crossed with an adapted wheat line from Kansas. By planting those seeds the next season, the farmers were perpetuating plants that had later-breaking rachises.

Their improved yield performance under drought stress conditions appears to be due at least in part to shifts in their rooting profile, whereby a greater proportion of root biomass is produced deeper in the profile (Lopes and Reynolds, 2011; Reynolds et al., 2008). The domestication of wheat (Triticum aestivum L.) from wild grasses in the Middle East is a fascinating story that resulted in one of the worlds most important and widespread crops.
