Some constraints on interspecific crossing of durum wheat with Aegilops tauschii accessions screened under water-deficit stress.

A total of 400 accessions of null Aegilops tauschii null null null Coss. (goat grass) collected from western Asia and the Caucasus were screened for the productive tillering capacity under rain-fed field conditions with the aim of developing new, synthetic hexaploid wheats having enhanced drought adaptation. Of these, 23 null Ae. tauschii null accessions were selected for interspecific crossing with two durum wheat varieties ‘Belikh-2’ and...
