Study summarizes the results of agronomical and malting parameters of spring malting barley varieties bred in the Breeding Station Sládkovičovo in the period of 1938-2010. Progress in breeding was reflected in the year-on-year increase in grain yield by 0.024 t/ha, thousand grain weight by 0.07 g, sieving fractions above 2.5 mm by 0.14 percentage points (pp), further, year-on-year reduction in plant height by 0.18 cm and nitrogenous substances content by 0.03 pp were recorded. Year-on-year increase in extract content by 0.055 pp, apparent final attenuation by 0.07 pp, Kolbach index by 0.11 pp and relative extract by 0.09 pp were identified. The year-on-year decline in β-glucan content in wort by 5.4 mg/l and increase in the value of friability by 0.3 pp were recorded. Wort color and wort color after boiling increased year-on-year by 0.008 unit EBC and by 0.014 unit EBC.
