Abstract

The inheritance of two taxonomically important characters was studied in hexaploid wheat species (2n = 6x = 42). The monogenic control of spherical grain was demonstrated for Triticum antiquorum Heer ex Udacz. The recessive gene controlling spherical grain in this species was localized to chromosome 3D by monosomic genetic analysis and was shown to be allelic to the s gene determining the same character in the endemic Indian species T. sphaerococcum Perciv. The T. antiquorum and T. sphaerococcum dominant genes controlling compact ears proved to be nonallelic to the corresponding T. compactum Host gene and were designated as C2. Problems of phylogeny and classification of hexaploid wheats are discussed.
