| 摘 要： | 低分子量谷蛋白亚基（LMW-GS）与小麦品质密切相关。为了给陕西小麦的品质改良提供参考依据,采用STS分子标记,检测了175份陕西小麦品种（系）Glu-A3和Glu-B3位点的等位变异组成。结果表明,陕西小麦Glu-A3位点存在4种等位变异,即Glu-A3a、Glu-A3b、Glu-A3c和Glu-A3d,分别占12.6%、1.7%、58.3%和27.4%;Glu-B3位点存在8种等位变异,即Glu-B3a、Glu-B3b、Glu-B3d、Glu-B3e、Glu-B3f、Glu-B3g、Glu-B3i和Glu-B3j,分别占4.6%、2.9%、45.7%、0.6%、2.9%、8.5%、4.0%和30.8%。在陕西不同地区小麦之间,两个位点等位变异的种类、组合及其分布比例存在差异,这可能与地区间不同的自然地理环境、饮食习惯、育种目标及亲本选择有关。

| Abstract: | Quality properties of wheat(Triticum aestivum L.) are strongly affected by low molecular weight glutenin subunits(LMW-GS).It is very important for improvement of wheat qualities to study the LMW-GS compositions and distribution in Shaanxi wheat cultivars and advanced lines.STS markers were used to detect the allelic variations of LMW-GS at Glu-A3 and Glu-B3 in 175 wheat cultivars and advanced lines from Shaanxi Province.Four allelic variations of LMW-GS were detected at Glu-A3 locus in Shaanxi wheats,i.e.Gl... |
