芒的缺乏被证明是作为一个显性性状遗传在四倍体小麦物种二粒小麦（Schrank）Schuebl。和T.硬粒小麦而在T.埃塞俄比亚草所有研究的物种的字符的单基因控制被证明。在二粒小麦和硬粒小麦中，该性状由位于染色体5A上的显性基因B1控制，而在埃塞俄比亚小麦中，该性状由一对隐性基因控制，我们将其命名为芒。隐性芒基因定位于T. aethiopicum与使用栽培品种Langdon的D-基因组二体置换系。
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.
