domestication of wheat

Evolving from an ancestral plant called emmer that still exists today, domestication of wheat was at least 12,000 years ago. tauschii accessions is to develop a Nested Association Mapping population (NAM), a method described for maize by Yu et al. Through access to collections of wild relatives, wheat scientists have helped overcome that bottleneck.

Its domestication coincides with the beginning of agriculture and since then, it has been constantly under selection by humans. tauschii (DD), but using a much broader range of Ae. Wheat: Vital grain of civilization and food security. In its strictest sense, it refers to the initial stage of human mastery of wild animals and plants. National Library of Medicine 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).

The earliest present evidence for the utilization of wheat comes from the Ohalo II site in Israel, where the wild, brittle tetraploid wheat Triticum dicoccoides, dated as 19,000 years old, was found, suggesting the initial steps towards sedentism and cereal agriculture (Kislev et al.

T. aestivum originated from a cross between domesticated emmer wheat T. dicoccum and the goat grass Aegilops tauschii, most probably in the south and west of the Caspian Sea about 9,000years ago. Wheats D genome ancestor is the goatgrass Aegilops tauschii, which occurs across a broad range of the Middle East and Asia from Syria to China. Emmer can grow in a variety of habitats from 100 meters below sea level to 1,700 meters above sea level, and can survive in places with annual precipitation of 200-1,300 mm. The main difference between wild forms and domesticated wheat is; domesticated wheat has larger grains with rind and semi-brittle stems.
