The results of a study of inheritance of the ''waxless'' trait in samp
les of two tetraploid wheat species, Triticum durum Desf. and T. polon
icum L., are represented. Dominance of the ''waxless'' trait, its mono
genic control, and the allelism of genes determining this trait are sh
own for all studied samples of both species. Location of the gene was
performed by the monosomic genetic analysis method, and chromosome 2B
was shown to be critical.
