Identification of Canadian barley varieties by high-throughput SNP genotyping

Abstract

Barley is a major grain crop in Canada and is used for generating malt, in addition to being used as human food and animal feed. Differentiating barley varieties is important for malt quality assurance and grain handling. Here, we present a DNA-based testing method for the identification of Canadian barley varieties. The method uses 24 custom TaqMan genotyping assays, which are analyzed using the high-throughput SmartChip system (Takara Bio Inc.). Using this method, we are able to distinguish 124 barley varieties commonly grown in Canada.
