| 摘 要： | 为给新疆小麦品质育种提供理论依据,利用Glu-A3、Glu-B3位点上的17个STS标记检测了185份新疆冬、春小麦品种Glu-A3和Glu-B3位点的等位变异。结果表明,新疆小麦品种以Glu-A3c、Glu-B3a和Glu-B3j亚基为主,其分布频率分别为64.86%、22.70%和17.84%。新疆冬、春小麦品种在Glu-A3位点上均以Glu-A3c亚基为主,分布频率分别为63.30%和67.11%;在Glu-B3位点上,新疆冬、春小麦品种分别以Glu-B3j和Glu-B3a为主,分布频率分别为22.02%和26.32%。新疆冬、春小麦农家品种亚基类型较少,冬小麦农家品种仅有5种类型（以Glu-A3c和Glu-B3i为主）,春小麦农家品种有10种类型（以Glu-A3c和Glu-B3d为主）。引进品种和自育品种亚基类型丰富,冬小麦引进品种以Glu-A3c和Glu-B3i为主,分布频率为12.84%和6.42%;春小麦引进品种以Glu-A3c和Glu-B3j为主,分布频率为17.11%和6.58%。冬小麦自育品种以Glu-A3c和Glu-B3j亚基类型为主,分布频率为45.87%和18.35%;春小麦自育品种以Glu-A3c和Glu-B3a亚基类型为主,分布频率为36.84%和18.42%。 |

| Abstract: | To clarify the allelic variation of Xinjiang wheat cultivars in Glu-A3 and Glu-B3 loci,and to provide theoretical basis for wheat quality breeding,the allelic variations in Glu-A3 and Glu-B3 alleles were tested among a total of 185 Xinjiang winter and spring cultivars using 17 STS markers.Our results showed: Xinjiang wheat varieties gave priority to with Glu-A3c,Glu-B3a and Glu-B3j,and the distribution frequency was 64.86%,22.70% and 17.84%,respectively.Xinjiang winter and spring cultivars in Glu-A3 alleles... |
