东北春麦区小麦品种(系)低分子量麦谷蛋白基因Glu-A3d和Glu-B3g的分子检测
Characterization of Glu-A3d and Glu-B3g Gene of Wheat Varieties(Lines)in the Northeast Spring Wheat Region by STS Markers
【摘要】 Glu-A3位点的Glu-A3d基因和Glu-B3位点的Glu-B3g基因是优质低分子量麦谷蛋白亚基(LMWGS)。为明确2个优质基因在东北春麦区小麦品种(系)中的分布情况,从而为强筋小麦育种和品质改良提供有用信息,利用Glu-A3d和Glu-B3g基因特异性STS标记检测了127份小麦品种(系)。结果表明:2个品种携带Glu-A3d基因,62个品种(系)携带优质基因Glu-B3g基因,占48.8%。
【Abstract】 Glu-A3 dand Glu-B3 gof Glu-A3 and Glu-B3 locus are high qulity gene for improving bread-making quality.In order to identify the wheat varieties(lines)carrying Glu-A3 dand Glu-B3 ggene in the northeast spring wheat region,to provide useful information for breeding programmer to improve bread-making quality and develop new varieties,127 wheat varieties(lines)were examined.The results showed that 2varieties carried the Glu-A3 dgene,and 62varieties(lines)carried Glu-B3 ggene,with a frequency of 48.8%.
