Plants, Genes & Agriculture: Sustainability through Biotechnology. These chromosome sets are designated the A, B, and D genomes, each with seven pairs of chromosomes. Domestication has genetically not only transformed the brittle rachis, tenacious glume and non-free threshability, but also modified yield and yield components in wheat. When wild wheat is ripe, the rachisthe stem that keeps the wheat shafts togethershatters so that the seeds can disperse themselves. Crop Wild Relatives in Genebanks. Synthetic hexaploids are not directly useful for wheat production because they are typically not adapted to the target growing area and they express wild species traits, such as poor threshing (i.e., the seeds do not separate easily from the enclosing glume tissue) and excessive lodging (Figure 3).

Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground. Both bread and durum wheat are domesticated forms of wild emmer. 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).
