It differs from wild wheat in that it has non-shattering spikes, an adaptation that allows the plant to better retain its seeds and to be harvested more easily.

A creative strategy for addressing the impoverished D genome diversity of common wheat is the development of synthetic hexaploid wheats (McFadden and Sears, 1946; Trethowan and Mujeeb-Kazi, 2008; Ogbonnaya et al., 2013).
