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). 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.

The process of developing synthetic hexaploid wheat is diagrammed in Figure 3. Wheat is an example of crop evolution through hybridization of wild species, which has led to a bottleneck in genetic diversity. The wheat production in 2021-22 crop year (July-June) had declined marginally to 107.7 MT from 109.6 MT in the previous year.
