Allelic Polymorphism Research of Barley Genes Bmy1 and LOX-1 that are Related to Brewing Characteristics of Grain

This work was aimed at allelic status identification of the barley genes Bmy1 and LOX-1 in the collection, consisted of 103 domestic and foreign cultivars, and also selection lines. Research of the collection was held using polymerase chain reaction (PCR) with a subsequent analysis of gene LOX-1 allelic polymorphism via restriction of amplification products. Results of the PCR and restriction were visualized using gel-electrophoresis method. It was defined that 63 barley cultivars would be promising for brewing because of their middle activity and thermostability of β-amylase in malt.
