Traits to Differentiate Lineages and Subspecies of Aegilops tauschii, the D Genome Progenitor Species of Bread Wheat

Aegilops tauschii Coss., the D genome donor of hexaploid wheat (Triticum aestivum L.), is most promising resource used to broaden genetic diversity wheat. Taxonomical studies have classified Ae. into two subspecies, ssp. and strangulata. However, molecular analysis revealed three distantly related lineages, TauL1, TauL2 TauL3. TauL1 TauL3 includes only tauschii, whereas both subspecies. This study aimed clarify phylogeny find traits that can differentiate between TauL3, or We studied morpho-physiological in 293 accessions covering entire range species. A total 5880 high-quality SNPs derived from DArTseq were for phylogenetic cluster analyses. As a result, we observed wide variation each lineage Despite this variation, no key discriminate lineages subspecies though some significantly different. Of 124 previously lacking passport data, 66 allocated 57 TauL2, one
