Collections of varieties of spring barley cultivars from Eastern European and Central Asian areas were analyzed by exon-specific PCR (EPIC) for β-amylase genes. The endosperm β-amylase gene (bamy1) was differentiated by the presence of 126 bp MITE insertion into intron 3, which is associated with low activity β-amylase. The findings suggest that a low level of genetic variation for bamy1 gene within climatic zones is associated with individual breeding program for each climatic zone.
