Molecular-genetic polymorphism of barley varieties (Hordeum vulgare L.) detected by the AFLP-method

Analysis of molecular-genetic polymorphism of barley varieties was performed using the AFLP-method. A system for identification and differentiation of barley varieties based on AFLP-markers was developed. Results of testing of 19 varieties indicate a high differential ability of the developed system. Identification of varieties can be conducted using one of two offered discriminatory sets of AFLP-markers. Based on the calculated genetic distances, a dendrogram of phylogenetic relations between varieties was constructed. The dendrogram revealed a separated origin of varieties of brewer and feed directions.
