[Allelic variants of the gene bamyl 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.
