Samples of three varieties of spring barley from 24 testing stations and two winter barley varieties from 13 testing stations were analyzed according to the standard ČSN 461100-5. The favorable course of weather in 2008 positively affected content of nitrogenous substances (11.9% and 11.4%) and starch (64.4% and 63.6%) in spring and winter barley caryopses. The occurrence of sprouted grains was minimal and the amount of the damaged grains was lower. Grain harvested in 2008 was bigger and its size was more homogenous. Portion of sieving fractions above 2.5 mm was on average 88.3 % in spring barley and 87.8% in winter barley. 2008 was a favorable year in terms of quality.Samples of three varieties of spring barley from 24 testing stations and two winter barley varieties from 13 testing stations were analyzed according to the standard ČSN 461100-5.
