Ancient wheat varieties have a coordination between aboveground and underground workings, but because of the characteristics that humans prefer, the plant has reshaped itself and established new networks. Without hulls, they germinate rapidly. CAS Transitions of forms. 41:205226, Kunzel G, Korzum L, Meister A (2000) Cytologically integrated physical restriction fragment length polymorphism maps for the barley genome based on translocation breakpoints. Other characteristics considered included spike size, growing season, plant height and grain size. The availability of reference genomes for wheat and some of its progenitors, as well as for barley, sets the stage for answering unresolved questions in domestication genomics of wheat and barley.

Domestication of wheat By Ahmet Meng on Wednesday, May 18, 2022 Wheat is a grain product with about 25,000 different varieties today. Also, todays wheat varieties have a shallower root system with a large portion of fine roots, so the biomass grows above ground rather than underground. Correspondence to Video 5.

Its domestication coincides with the beginning of agriculture and since then, it has been constantly under selection by humans. One possible way that might have occurred is that farmers harvested wheat after it was ripe, but before it self-dispersed, thereby collecting only the wheat that was still attached to the plant.
