| Description
| - The study presents the results of research on the use of barley caryopses hardness for prediction of the malting quality. Grain hardness was determined by three methods: Particle size index (PSI), hardness according to Brabender (BRA) and grain milling energy (GME). The correlations among methods for determining the kernel hardness were estimated as well among selected technological traits of barley and malt and kernel hardness. Significant correlations were found among PSI values and Final attenuation of laboratory wort from malt (0.73*) a Glycidic extract (0.70*). Values of kernel hardness measured by BRA significantly correlated with Final attenuation of laboratory wort from malt (-0.80*) and Soluble nitrogen of malt (0.64*). Grain milling energy values were statistically significant correlated with Nitrogen content in malt (0.64*). The preliminary results confirmed the possibility to use kernel hardness for prediction of some malting quality traits. Further studies will be done on larger number of

- Přesné stanovení kvality ječmene mikrosladováním je pro šlechtitelskou selekci nákladné, a proto jsou hledány vhodné levné metody odhadu kvality. Cílem bylo zjistit, zdali je možné podle úrovně tvrdosti obilek ječmene selektovat na sladovnickou kvalitu. Byly analyzovány vzorky obilek souboru deseti odrůd ječmene. Tvrdost obilek byla stanovena metodami PSI (Particle size index), tvrdostí dle Brabendera (BRA) a metodou stanovení energie potřebné k mletí vzorku (GME). Vzorky byly následně mikrosladovány a u sladů byly stanoveny vybrané technologické parametry. Byly zjištěny statisticky průkazné rozdíly mezi odrůdami v úrovni tvrdosti. Byly stanoveny korelace mezi úrovní tvrdosti a vybranými technologickými parametry ječmene a sladu. Hodnoty PSI byly v průkazné korelaci s dosažitelným stupněm prokvašení (0.73*) a glycidovým extraktem (0.70*). Hodnoty BRA byly v průkazné korelace s dosažitelným stupněm prokvašení (-0.80*) a obsahem rozpustného dusíku ve sladu (0.64*). Hodnoty GME byly ve významné korelac (cs)
