| Research Abstract |
Genetic variation was studied in Aegilops tauschii covering its whole distribution area. Although only one cluster was recognized in chloroplast DNA variation, two distantly related lineages were found in nuclear DNA. The two lineages were supposed to establish through several million years separation. Similar genetic structure was also detected in wild barley, Hordeum vulgare ssp. spontaneum. It was shown that population division through evolutionary time is important to clarify genetic variation at present.
