Khorassan wheat (Triticum turgidum ssp. turanicum Jakubz em. A. Löve & D. Löve) is an ancient tetraploid wheat that was grown in the Mediterranean region and Near East. Sixteen lines differing in the composition of high-molecular-weight glutenin subunits (HMWGs) were evaluated for SDS-sedimentation volume and quality index (QI). The data suggested that the two subunit combinations detected in the examined materials at the Glu-B1 locus showed differences in both characteristics (relatively higher levels at the presence of the subunit combination 7+15 compared to 6+8). Weak gluten is in general characteristic of this wheat species. It could be used in a better way for other baking applications than for the pasta industry.Keywords:
