Abstract
Given the limited genetic diversity in crop species, the use of wild relatives of crop plants provides breeders with a rich and diverse gene pool of new and desirable alleles. Bread wheat, as the most important cereal, is cultivated worldwide. This strategic crop possesses diverse genotypes that are widely utilized in breeding programs. However, in recent years, the genetic diversity of cultivated wheat has declined due to factors such as intensive breeding and repeated selection. Consequently, the exploitation of genetic resources from wild relatives, particularly species within the genus Aegilops—notably Aegilops tauschii, which harbors a wealth of beneficial genes—has become both necessary and imperative for sustaining and enhancing wheat improvement efforts. Multivariate statistical analyses are performed on morphological data with the aim of grouping and separating genotypes. The aim of the present study was to apply simple and multivariate statistical methods to assess the genetic diversity of 10 ecotypes of Aegilops tauschii collected from different regions of Iran under optimal moisture conditions so that the information obtained can be used to utilize the diversity of this germplasm in future wheat breeding programs.
