Tibetanum were more abundant, which can be used to broaden the genetic basis of common wheat. Cluster analysis exhibited that wild emmer had a closer consanguine relationship to hexaploid wheat, as compared to Aegilops tauschi. In addition, it was found that there was a closer genetic relationship in chloroplast genome of common wheat and T. petropavlavskyi, which indicated that T. petropavlavskyi probably derived from the backcross between common wheat and Polish wheat.
