Dormancy of barley belongs today to the parameters of malting barley quality evaluation. The following malting barley varieties were assessed - Jersey, Kompakt, Scarlett, and Tolar, since 2002 a new variety Prestige and in 2004 also the variety Malz, they are the supporting malting varieties. Samples were selected based on the following quality parameters: germinative capacity of barley is higher than 96% and protein content in barley is from 10 to 12% in dry matter, in 2004 however the bottom limit was lowered to 9.5% due to generally lower protein content in barley. Intensity of barley dormancy was checked by determination of germinative energy on Petri dishes with 4 ml of water after 72 hours in a thermostat at 20 °C. Determination of germinative energy of malting barley was done in 2001 to 2004 always 6 weeks after harvest. Germination rate was determined by the calculation from the data of germinative energy.Dormancy of barley belongs today to the parameters of malting barley quality evaluation.
