In this study, in order to select genotypes with desirable quality and agronomic traits as parental in the Cereal Research Department, SPII s breeding programquality of seed storage proteins were investigated in 46 different bread wheat lines or cultivars. Haploid breeding methodology was then applied to achieved absolute homosigocity and to increase the selection efficiency. Using the selected parental lines, crosses were n made between wheat and maize resulting in development of 151 Doubled haploid (DH) lines. The Dh lines along with their parents and cv.s Alvand and Sayren were then studied for their high molecular weight glutenin sub-unit. . In order to separate the glutenin subunits, SDS-PAG method with 10% gel was used and the total of 15 subunits in three gene loci were observed. Subunit 5+10 with 57.33 percent and subunit 17 with 0.77 percent had the highest and the least frequency. In the lines studied, several gene loci, which were unexpected, were observed. Finally the lines under investigation were graded for glutenin quality. A number of doubled haploid lines had the highest quality grade compared with their parents and F1 seeds. Additionally, these genotypes were planted under field conditions for screening against diseases and other unfavorable traits.
