安徽省小麦产业体系展示品种HMW-GS组分及GMP的研究

为了解安徽省淮北及黄淮麦区的小麦加工品质,以52个安徽省小麦产业体系展示品种为材料,分析了供试小麦品种HMW-GS的组成和分布、谷蛋白聚合体(GMP)含量、小麦蛋白质含量、Zeleny沉降值及湿面筋含量。结果表明,52个供试小麦品种的HMW-GS变异类型众多,共发现13种变异类型,包含6种优质亚基类型;共出现了21种HMW-GS组合。按照GMP、蛋白质、湿面筋含量及Zeleny沉降值可将52个供试品种分为4类。供试品种的品质评分介于4~10分之间,平均7.4分。基因位点Glu-A1含有1亚基的品种,GMP含量高于含有Null亚基的品种。

Study on the Composition and Distribution of the HMW-GS and GMP Content of the Wheat Varieties from Wheat Industrial and Technological System in Anhui Province

The processing quality of wheat is closely related to high molecular weight glutenin subunit (HMW-GS). In order to improve wheat processing quality in the north along Huaihe river in Anhui province and Huang-Huai area,52 wheat varieties,which were provided by the wheat industrial and technological system in Anhui province,were selected as materials to analyze the diversity of HMW-GS,determine the gluten polymers(GMP) content,and analyze the contents of wheat protein and wet gluten as well as the Zeleny sedimentation value. The results showed that the variations of HMW-GS in these wheat varieties were rich,and 13 types of variations were found,including six subunits related to good quality. There were 21 HMW-GS compositions.52 varieties were clussified to 4 type according to content of GMP,protein,wet gluten and Zeleny value.According to the quality scoring method by Payne,the score ranked from 4 to 10,with the average of 7.4.And the GMP content of varieties containing Glu-A1 alleles was higher than that of the Null allele.
