东方小麦(Triticum turanicum Jakubz.)醇溶蛋白遗传多样性分析

Genetic Diversity of Triticum turanicum Jakubz. Based on Gliadin Analysis

为了进一步利用东方小麦(TriticumturanicumJakubz.)遗传资源,对来自埃塞俄比亚、伊拉克、伊朗、阿塞拜疆、阿富汗、摩洛哥等国家共87份东方小麦醇溶蛋白位点的遗传多样性进行了分析。结果发现,供试材料存在丰富的遗传变异,87份材料共产生72种谱带类型,分离出33条带纹,每份材料可电泳11～2 2条带,平均16条;在α、β、γ和ω四个区均差异较大,分别有16、11、2 0和2 0种谱带变异类型。聚类分析发现,醇溶蛋白揭示的材料间遗传多样性与其地理来源有一定关系。

To utilize the genetic resources of Triticum turanicum in wheat improvement,genetic diversity of gliadin in 87 accessions from different countries was investigated. Thirty-three gliadin bands were detected in a total of 72 gliadin patterns. Eleven to 22 gliadin bands were found in each accession,with an average of 16. In α、β、γand ω zones, 16,11,20 and 20 band combinations were observed, respectively. These results suggested that high levels of gliadin variations were presented in T. turanicurn. Cluster analysis indicated that the genetic diversity of T. turanicum was associated with its geographical distribution.
