[Molecular-genetic polymorphism of barley (Hordeum vulgare L.) cultivars detected with AFLP method].

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