摘要: 利用测序技术筛选和确认4?个可以区分7?种大麦麦芽的单核苷酸多态性(single nucleotide polymorphisms,SNP)位点,并建立区分图谱。同时,利用竞争性等位基因特异性聚合酶链式反应检测技术对预混样品进行定量测试,其检测的结果与真实性之间相对误差小于3%。该技术的建立对大麦麦芽纯度检测提供方法,对大麦麦芽SNP指纹数据库的完善提供了数据支持。

Abstract: In this study, 4 single nucleotide polymorphisms (SNPs) were screened out and identified by sequencing for the discrimination of 7 malt varieties. Furthermore, discrimination profiles were also established using SNP based kompetitive allele specific PCR (KASP) assay. Quantitative analysis of known mixed samples was carried out using the KASP assay with a relative error less than 3% between the measured and actual values. The KASP assay is useful for the enrichment of malt SNP fingerprint database.

Key words: malt, kompetitive allele specific PCR (KASP), qualitative detection, quantitative determination
