Abstract

In this study, 183 lines/cultivars of bread wheat used in crossing blocks of breeding programs for temperate and cold climatic zones of Iran were analyzed for high molecular weight glutenin subunits (HMW), and their alleles and quality genome scores were determined. Results showed that 60% of the genotypes had a quality genome score of 8-10 and 40% less than 8. In case of Sorkhtokhm and Kavir cultivars and line Kauz/Sorkhtokhm an allelic combination was observed in Glu-D1 locus which resembles 2+10. This allelic combination was determined in this report with 2.1+10*. Since the 183 genotypes of crossing nursery of temperate and cold climate breeding programs had been grouped to 17 subsets based on different characteristics, the results of this study determined several genotypes within each group with higher score for quality. These highlighted genotypes could be used for development of new germplasm with better bread making quality.
