title: [Inheritance of awn absence in tetraploid wheat species].
abstract: Awn absence was shown to be inherited as a dominant character in the tetraploid wheat species Triticum dicoccum (Schrank) Schuebl. and T. durum Desf. but as a recessive one in T. aethiopicum Jakubz. The monogenic control of the character was demonstrated for all studied species. In accessions of emmer and durum wheat, the character is controlled by the dominant gene B1, located on chromosome 5A, and in Ethiopian wheat, by a recessive gene, which we designated as awn. The recessive awn gene was localized on chromosome 3B of T. aethiopicum with the use of D-genome disomic substitution lines of cultivar Langdon.
