In 2010 almost all studied varieties reached the value of germination energy 3 weeks after achieving full maturity higher than 85 %. Only two varieties (Aksamit, Marthe) had the value of germination energy lower than 85 %. In following weeks the value of germination energy declined in some varieties. The decline in the values of germination energy indicates that grain of some varieties was heavily affected by sprout damage during harvest. In 2010 problem with sprout damage was more frequent compared to previous years. The varieties differed considerably in the intensity of germination characterized by germination rate and index. In the harvest year 2010, germination rate 3 weeks after reaching full maturity, was higher than 65 % nearly in all varieties. Only the varieties Aksamit and Marthe had germination rate lower than 65 %. Variability of germination energy and parameters describing germination intensity was significantly affected by a locality.In 2010 almost all studied varieties reached the value of germination energy 3 weeks after achieving full maturity higher than 85 %.
