摘　　要：应用SSR分子标记技术对4份来自美国的小麦研究材料的高蛋白含量基因GPC-B1进行分子标记分析。通过引物筛选和标记研究,其SSR分子标记为Xuhw89122。为鉴定其分子标记分析结果,对所有的小麦研究材料进行蛋白质含量的测定,来自美国的4份研究材料之一的PI638740的蛋白质含量高达20.41%,明显高于其他研究材料。田间观察结果显示,PI638740的成熟期比别的研究材料提前衰老一周左右。本研究将为转移控制小麦高蛋白质含量的基因到其他优良小麦品种(品系)中、推进小麦育种进程及改进小麦育种技术提供理论依据。The high protein content gene GPC-B1 was marked by SSR markers in four high protein wheat from America. The GPC gene was on the short arm of chromosome 6B from Triticum turgidum ssp.dicoccoides. Its SSR markers was Xuhw89122 .The protein of PI638740 content was tested for 20.41%. Obviously, the protein content of one of the four materials was highest. The results in field showed that it matured more previously round a week compared with the only other wheat. The markers acquired would offer an effective elected means to transfer the high protein gene to other wheat materials.
