Part of wheats adaptability is due to the fact that it occurs both as winter habit varieties (requiring a cold period of 6 to 8 weeks to trigger reproduction), and spring habit varieties (not requiring the cold period). Other scholars have questioned the date, and the aDNA identification, saying it was in too good a condition to be that old. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. Because of their biological and agricultural importance, we have deternied a more precise location of Br-A1 and Br-B1 on . 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. II. But that naturally useful brittleness doesn't suit humans, who prefer to harvest wheat from the plant rather than off the surrounding earth.

While some scientists argue that this is a fairly rapid process of several centuries; Others argue that the process from the cultivation of wheat to its domestication is almost 5,000 years old. (2008). (2021, June 28). 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). Domestication Domesticates are species of plants and animals that show recognizable changes in morphology away from wild phenotypes. Shifts in Plant Functional Strategies over the Course of Wheat Domestication, Sedimentary DNA from a Submerged Site Reveals Wheat in the British Isles 8000 Years Ago.
