- 摘要:
- 低分子量麦谷蛋白亚基约占小麦谷蛋白的80%，对小麦品质影响很大，为明确各亚基与品质的关系，促进小麦育种工作，采用PCR方法检测190个中国小麦微核心种质Glu-A3位点等位基因。结果表明：共检测到Glu-A3a～Glu-A3g 7种基因类型，且以等位亚基c为主。SDS沉降值测定显示，c亚基对品质作用较小，但所占比例最大。由此可见，我国小麦种质资源以劣质亚基为主，引进优质亚基可成为我国小麦品质改良的重要途径。
- Abstract:
- About 80% glutenins are made up of low molecular weight glutenin subunits,and they play a very important role in wheat quality.In order to clear the relation between the subunits and quality and promote the wheat breeding work,190 wheat mini core germplasms were detected by using PCR.The data showed there were 7 alleles at Glu-A3 locus included the highest c subunit.SDS sedimentation value indicated that c subunit which was smaller effect on wheat quality had the biggest proportion.The wheat germplasm resources in our country were still inferior.The introduction of high quality subunits would become an important way of improving wheat quality for China.
