Abstract-An experiment was conducted at the Islamic Azad University, Ardabil Branch in 2013. Significant diversity with regard to the three Glu-A1, Glu-B1, Glu-A1, and Glu-B1 subunits of 57 wheat landraces of the Northwest of Iran by SDS-PAGE. And Glu-D1 loci were observed. In Glu-A1 locus 1, 2 * and zero alleles were found with a frequency of 10.5, 57.9 and 31.6 percent. In Glu-B1, 7 alleles were detected, in which the 7 + 8 allele was the most frequent allele. In Glu-D1 locus, 2 + 12 and 5 + 10 were recognized with a frequency of 68.4 and 31.6 percent. The high quality 5 + 10 subunit pair was recognized in 9 landraces. The quality score of the landraces were ranked from 4 to 10 indicating a large genetic diversity among the landraces. Landraces numbers 1, 20, 23, 27, 51, 52, 36 and 49 had the best composition of the HMW glutenin subunits and consequently the highest quality score.
