Allelic variants of the gene bamy1 barley in eastern european and central asian areas

SUMMARU. The collections of varieties of spring barley cultivars from the Eastern European and Central Asian areas were analyzed by exon-specific PCR (EPIC) for β-amylase genes. The endosperm β-amylase gene (bamy1) was dif-ferentiated by the presence of 126 bp MITE insertion into intron 3 that is associated with low activity β-amylase. The findings suggest that a low level of genetic variation for bamy1gene within climatic zones is associated with individual breeding program for each climatic zone.
