Abstract:   (217 Views)
   In order to evaluate the genetic diversity of quantity and quality of wheat, 30 varieties and lines of wheat were evaluated by SDS-PAGE methode. The banding pattern of glutenin proteins extracted from seed indicated the presence of three subunits in the Glu-A1 gene site, four subunits at Glu-B1 and two subunits at the Glu-D1 site. In the Glu-A1 site, the alleles of the Null, in Glu-B1 site, sub units of 8 + 7 and 18 + 17 and in Glu-D1 site, subunits of 5 + 5 had a the heighest frequency. In this research, the genotypes of Zarin,Pishgham, Azar, Rasoul, Tous, 26 and 29 with genomic score of 10 were identified best genotypes in terms of baking quality. Based on regression analysis of data, allele 2* of loci Glu-A1 explaned 43% of the changes in moisture content, Alleles 2* of Glu-A1 and allele 10 + 5 of Glu-D1 loci justefied 52% of total seed protein variation. Allels 10 + 5 of Glu-D1 locus, allocated 43 percent of Zeleny number variation. Allele 8 + 7 of Glu-B1 locus, showed 40% of hardness variation. Finally alleles 16 + 13 of Glu-B1 locus justifed 38 percent of the starchcontent.
