结合CAWGES软件 ,用改良的pH3.2A PAGE技术绘制并构建了我国北方冬麦区建国后不同时期的主栽品种及其部分骨干亲本共 6 8个品种的标准麦醇溶蛋白指纹图谱及其数据库。并利用数据库在图谱分析、品种鉴定及血缘关系研究等方面进行了应用探讨 ,为建立小麦核心种质及品种鉴别提供了有效手段。 Combined with CAWGES software, the standard gliadin fingerprinting and database of 68 varieties of main cultivars and some of their key parents at different stages after the foundation of winter wheat in northern China were constructed and constructed with the improved pH3.2A PAGE technique. . The application of the database in the aspects of spectrum analysis, variety identification and kinship research has been explored, which provides an effective method to establish wheat core collection and variety identification.
