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
