摘　　要：本试验研究近3年来中国不同区域旱地小麦蛋白质品质变化规律,研究结果可为小麦品种改良和食品加工提供理论依据。通过对2003年-2009年我国4个国家区域试验冬、春小麦旱地组的217个区试品种(系)小麦样品的籽粒蛋白质含量、湿面筋含量、沉淀值、稳定时间和最大拉伸阻力进行分析。结果表明:旱地春小麦的蛋白质含量、湿面筋含量、面团稳定时间平均高于旱地冬小麦,3项指标以东北春麦旱地组最高;按照稳定时间、蛋白质含量、湿面筋含量分类,强筋和中筋品种比例分别为12.4%和30.9%,弱筋小麦品种只占0.5%。比较9个品质指标品种间的变异,以面团稳定时间最大、容重最小。稳定时间的变异约为蛋白质和湿面筋含量的10倍以上,而后两者变异程度相近。The objective of this study is to analyze the changes in grain protein quality of wheat in different planting regions in China. It might provide scientific direction in breeding improvement and food processing of wheat. Total of217 winter and spring wheat cultivars（ lines）,originated from the national wheat regional trial in rainfed farmlands from2003 to 2009,were conducted to analyze the grain protein quality. The test phenotypes were associated with protein content,wet gluten content and sedimentation value,stabilizing time and maximum resistance. The results showed that protein content,wet gluten content and dough stabilizing time of spring wheat cultivars were averagely higher than those of winter cultivars in rainfed conditions. Higher values of these three characters were also found in the northeast spring wheat group. By clustering analysis of protein content,wet gluten content and dough stabilizing time,the strong,medium and weak gluten-strength wheat cultivars were taken the proportion to 12. 4%, 30. 9% and 0. 5%,respectively. In nine quality traits among different cultivars,the variation of the stability time was the largest,but the least in the testing weight. The variation of the dough stabilizing time was up to ten times as much as protein content and wet gluten content,while the latter two showed approximate variation. The poor gluten was a common problem of the wheat quality in rainfed regions in China,and more effective measures should be taken for quality improvement.
