To study the genetic diversity land races durum wheat in terms of agronomic traits and low molecular weight, glutenin test was carried out in agricultural research station of Ardebil Islamic Azad University in the crop year 2011-2012. 34 wheat grain land races plant material, including the North West area of Ardabil were prepared. Test complete block design with three replications in the agricultural sector, along with three checks was carried out. Genetic diversity by SDS-PAGE electrophoresis mass of the low molecular weight was performed to identify it. The present study showed that there are agronomic traits among the masses acceptable variation. The results showed that 6 in place of Glu-A3 allele, the locus GLU-B2 only two alleles at Glu-B3 locus alleles were six. Different alleles at locus GLU-A3 and plant height, peduncle length, biomass plants and SDS sedimentation were linked, so that genotypes having allele e, d and h of biomass per plant were more than these alleles that biomass can be used for selection. Also genotypes having allele b and c has a lower height than the other genotypes, thus from these alleles can be used as a marker for selection of dwarfism. B allele genotype has a lower height SDS was precipitated, while there was no significant difference between the alleles. GLU-B2 locus alleles of different traits, awn length, grain weight and SDS sedimentation so that genotypes containing alleles associated has awn length and weighing a hundred more seeds and less sedimentation volume were compared with allele b so this allele also can be used as a marker in the selection of these traits.
