Description Within the last 13 000 yearsmany crop species were domesticated and spread to a range
of agri-ecological environments, varying by species (Hancock 2012a).There was manual
selection for both food and agronomic characteristics, and natural selection for adaptation
to new agro-ecological environments. Such selection was affected by available gene
pools, continuing sources of genetic diversity from wild relatives andmutations, natural
selection pathways fromstabilising to directional, and both allo- and auto-polyploidy, to
result in unique gene pool patterns for each crop (Hancock, 2012b; Cortes et al., 2013).
Thedistribution of wheatwas expanded greatlywith the addition of the Aegilops tauschii
D genome to tetraploid durum wheat, thereby enabling hexaploid wheat to adapt to a
much wider agroecological range from the subtropics to high latitudes, and to provide
a wider diversity of food uses (Hancock, 2012c)...
