Breeding work for the development of the new hulless winter barley genetic resources has mainly focused on increasing grain yield and important agricultural characters (winter hardiness and resistance to main leaf diseases). Gradual improving of the grain yield components has reached to new hulles winter barley materials with comparable yield to the check variety Monaco. On the bases of number of zones, relative mobility and staining intensity there were identified and characterized allelic blocks of the hordein electrophoretic banding patterns in new perspective hulless winter barley materials and their parents. A different degree of polymorphism in the new materials has demonstrated the origin of the hulless material (hordein patterns of spring and/or winter barley varieties) as well as the direction to the selction from heterogenous populations. The hordein electrophoretic spectra of the individual plants, chosen from the best line KMOZ2 in year 2001, certificate the orientation to the homegoneous material, if of spring character.
