| الملخص: | Wheat is a monocot belonging to the family
poaceae. It is an important cereal crop
consumed as a staple food after maize.
Wheat (Triticum spp.) is a grass from the
Fertile Crescent region of the Near East (the
Karacadag Mountains in south-eastern
Turkey) which is now cultivated worldwide.
There exists nearly 24 species of Triticum.
Einkorn wheat (Triticum monococcum) and
emmer/durum wheat dates back to 8000-9000
sc. Einkorn is diploid (AA) and durum is deri-
ved from wild emmer, Triticum dicoccoides
(AABB), which resulted by natural selection
from the hybridization of Triticum urartu and
Aegilops speltoides. Bread wheat, which is
hexaploid (AABBDD), evolved from either
wild or domesticated emmer hybridized with
another diploid grass, Aegilops cylindrica.
Synthetic hexaploid wheats have been devel-
oped by crossing wild goat grass, Aegilops
tauschii (D genome sps.), with durum wheat
to create more genetic diversity. Synthetic
wheats are not easy to thresh as toughened
glumes enclose the grains tightly (http://en.
wikipedia.org/wiki/Wheat#History). |
