Abstract

WHd relatives of common wheat (Triticum aestivum L.) and durum wheat (T. turgidum L. var durum) are valuable sources of desirable characters for improving wheat cultivars. Since the genus AEGILOPS L. bears a close and important relationship with durum and bread wheat, more detailed study of them should also be beneficial in understanding these polyploid wheats. In this study, seven durum wheat landraces were crossed as the female parent with 32 accessions of AEGILOPS belonging to five species (Ae. squarrosa, Ae. crassa, Ae. triuncialis, Ae. caudata and Ae. cylindrica). Spikes were harvested 12-15 d after pollination for embryo rescue and some spikes were left to evaluate the formation of direct AMPHIHAPLOID seeds. AEGILOPS species had a major influence on CROSSABILITY (seed set), embryo culturability and plant recovery. The highest efficiency of AMPHIHAPLOID plant recovery from rescuing embryos (42.1 %) was obtained from TRITICUM TURGIDUM (4x)×Ae. crass a (4x). This was followed by TRITICUM TURGIDUM (4x)×Ae. crassa (6x) cross (37.8%). An efficient direct synthesis of viable AMPHIHAPLOID seeds from crosses between durum wheat landraces and Ae. Crass a (4x) originating from western Iran is also reported. The high CROSSABILITY together with the direct germination of F1 hybrid seeds of Ae. crassa (4x), provides new evidences concerning close phylogeny of this species and the polyploid species of wheat.
