 In order to evaluate genetic diversity of wheat landraces of Zanjan region of Iran by the electrophoresis of seed storage proteins, 30 accessions from this area were provided from national plant gene bank of Iran in Karaj. Electrophoresis of high molecular weight (HMW-GS) and low molecular weight (LMW-GS) glutenins was undertaken by SDS-PAGE with sequential extraction. For HMW-GS, three tetraploid accessions including TN-11372, TN-11734 and TN-11743 were identified which did not contain any alleles of Glu-D1 locus. In Glu-A1 locus, 83.33% of the landraces had null allele and 16.67% of them had subunit 2*. In Glu-B1 locus, subunits 7+8 had highest frequency (36.67%) and alleles 13+16 and 21 showed lowest frequency (3.33%). One exceptional subunit related to this locus was characterized in accession TN-11384 which named 6*. In Glu-D1 locus, subunits 2+12 were identified in 77.78% of accessions and subunits 3+12 were characterized in other accessions. In Glu-3 locus, 12 LMW subunits were observed with different mobilities and genetic diversity index (H) was 0.844. The high diversity characteristics of seed storage proteins may be useful in identification of varieties and ploidy levels and determining bread making quality in order to improving wheat quality characteristics.

In present research, genetic diversity of gliadins among 30 wheat landraces belong to region of Zanjan-Iran, was studied by Acid-PAGE technique. Totally 54 polymorphic gliadin bands were identified. The highest frequency was related to gliadin band 46 witch observed in 90% of wheats. Also gliadins 12.5 and 15.5 were observed in 86.7% of the wheats. Genetic diversity of the wheats based on total gliadin found to be high (H=0.967). Highest and Lowest genetic variation related to omega-gliadins (H=0.917) and gamma-gliadins (H=0.781) respectively. Wheats of Zanjan showed diversity in terms of gliadin bands number (11-25 bands). The entire wheats, showed specific gliadin pattern. Totally, 29 omega-gliadin patterns, 15 gamma-gliadin patterns, 22 beta-gliadin patterns and 23 alpha-gliadin patterns were observed. Cluster analysis could separate three tetraploid genotypes TN-11372, TN-11734, TN-11743 from hexaploids. These results indicate that gliadin proteins analysis is useful for evaluating of genetic diversity, characterizing of wheat genotypes and separating of different ploidy levels. Manuscript profile
