Abstract: To improve the efficiency of high quality wheat breeding program,clarify the composition of HMW-GS and Gliadin in the early generation,296 lines from the wheat maize cross were analyzed useing SDS-PAGE method in this experiment,along with this Gliadin were analyzed useing A-PAGE method.A statistics showed that female parent Heng 09-6324 carried null,7+9,2+12 subunits,and were 1BL/1RS translocation lines with Sec-1 characteristic band.Male parent Shiluan 02-1 carried 1,7+9,5+10 subunits,and were non 1BL/1RS translocation.Six types of HMW-GS all originated from parents were identified from 296 DH lines.The frequency of subunits 5+10 which positively related to bread baking quality was 35.13%.A statistics showed that in the A-PAGE the type of translocation of the DH lines accounted for 54.05%,and the percent of lines with subunits 1 and 5+10,but non Sec-1 translocation were 15.20%,these lines could be used as new germplasm for quality breeding.The paper indicated that that the method of half-seed SDS-PAGE and A-PAGE which could be used to identify and select excellent plants in early generation breeding effectively.
