引自21个国家的硬粒小麦品种54份,分别种植在哈尔滨、北京、银川和西宁。分析硬粒小麦蛋白质含量与生态环境的关系,小麦蛋白质含量与灌浆期日均气温呈正相关,与生育期、灌浆期天数、千粒重呈负相关。引自西班牙的D152编号品种在4个生态点上蛋白质含量均高达18%以上,筛选出一些适应性广的高蛋白含量的硬粒小麦品种。 54 durum wheat varieties from 21 countries were planted in Harbin, Beijing, Yinchuan and Xining respectively. The relationship between the content of protein and ecological environment of Durum wheat was analyzed. The protein content of wheat was positively correlated with the average daily temperature at grain filling stage, and negatively correlated with the number of days of grain filling and 1000-grain weight. The protein content of varieties D152 from Spain was higher than 18% at four ecological points, and some high-protein durum varieties with wide adaptability were selected.
