Allelic variants of the gene bamy1 barley in Eastern European and Central Asian areas

Abstract

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