Abstract: As the donor species of D genome in common wheat(Triticum aestivum),Aegilops tauschii has abundant genetic diversities,which provides valuable genetic resources for improving common wheat since the genetic background of T. aestivum is becoming increasingly consistent. This paper systematically summarizes the genetic information of A. tauschii based on the recent researches of domestic and overseas,including its genetic diversity and utilization in wheat breeding. This review is aimed to provide references for better utilizing the germplasm resource of A. tauschii.

Key words: Aegilops tauschii Coss., Triticum aestivum, genetic diversity, genome
