Abstract	Hull-less mutants of spring barley obtained by mutation induction from the hull-less breeding line 1N/86 constituted the material for the performed studies. Two chemomutagens, N-nitroso-N-methylurea [N-methyl-N-nitrosourea] (MNU) and sodium azide (NaN SUB 3 ), were used for the treatment. Among the mutants 19 forms, representing different morphotypes and yielding ability, were chosen to field experiments performed in 2000-02. The paper presents genetic variation of yielding and yield structure parameters of the mutants and their initial form. The results were statistically elaborated considering the years of the experiments and the analysed traits. Compared to the initial forms, the mutants were characterized by a broad spectrum of variation for the traits. Generally, in the three years of experiments, the mutants showed lower yielding ability and decrease of the yield structure parameters. In spite of this, several mutants yielded above their initial form and exceeded it in the yield structure traits. They may constitute an interesting initial material for breeding programmes of hull-less barley
