Applicability of polyacrylamide gel electrophoresis and isoelectric focusing of hordeins for discrimination of six two-rowed winter barley varieties (Angora, Sladoran, Rodnik, Rex, Martin and Barun) has been investigated. Hordeins extracted from dry grains and green malt of barley varieties were separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis in gradient gel of 8-18% T, and by isoelectric focusing in pH gradient of 3.5-9.5 and 5.5-8.5, respectively. In all separation experiments better resolution of proteins was achieved with dry grain extracts, than with malt extracts. Angora, Sladoran and Martin variety could be distinguished from other varieties by differences in hordein patterns obtained by gradient gel SDS-PAGE (8-18% T), and Angora, Sladoran, Martin and Rodnik by isoelectric focusing in pH gradient 5.5-8.5
