The material for performed studies comprised 19 hull-less barley mutants, their initial form 1N/86, as well as six hul- led forms – three fodder and three malting cultivars. In field trial the mutants and their initial form were analysed for yield structure traits, and for all objects for geometric properties of grains and their resistance to squashing as expressed by stress, strain, and energy. As compared to the initial form, the mutants were characterized by broader genetic variability of yield structure. It allowed to select a few mutants with higher grain yield per plot as well as higher yield structure parameters. A broad variation was also observed for geometric properties of grains and their resistance to squashing. For those traits great differences were noticed not only among the hull-less mutants but also among the hulled cultivars. Based on obtained results a comparison between both groups of barley forms was performed.
