In this respect, gliadins could be an important tool in assessing genetic variability as protein markers. Thus, genetic diversity of gliadin protein patterns in seventeen populations of </span></span><span lang="EN-GB" style="color: #221e1f; line-height: 200%; font-family: &quot;Garamond Premr Pro&quot;,&quot;serif&quot;; font-size: 10pt; mso-bidi-font-family: &quot;Garamond Premr Pro&quot;; mso-bidi-font-style: italic;">Aegilops cylindrica </span><span style="font-family: Times New Roman;"><span lang="EN-GB" style="color: #221e1f; line-height: 200%; font-size: 10pt;">collected from northwest of Iran were investigated using acid polyacrylamide gel electrophoresis. Results showed that the highest number of bands in the electrophoregrams were related to the ω type of geliadins. Conversely, the lowest number of bands were pertained to the β type of gliadins. Genetic diversity between populations was greater than within population variation. Assessment of total variation for the three gliadin types indicated that the highest total variation was related to β type while, the lowest one was belonged to ω type. Cluster analysis using complete linkage method divided populations into two separated groups in which genetic diversity does not follow from geographical distribution.</span><strong></strong></span></p><span style="font-family: Times New Roman; font-size: small;"> </span
