Drought stress is one of the major factors affecting in wheat yield and grain quality. In order to investigate how drought stress might infl uence wheat quality during grain fi lling, three wheat cultivars Gaocheng 8901, Jagger and Nongda 3406 were subjected to drought stress during the grain fi lling stage. Neither globulin and glutenin, nor the relative percentage of amylose signifi cantly changed following drought treatments, whereas albumin and gliadin concentrations did. The SDS-sedimentation, which has a strong linear correlation with wheat baking quality was markedly decreased following drought stress. These results indicated that drought had an adverse effect on wheat quality. In order to investigate the protein complexes in the wheat fl our, the data from native PAGE and SDS-PAGE were combined and a total of 14 spots were successfully identifi ed, and of these eight protein types were determined to be potential complex forming proteins.
