Study was focused on the evaluation of the course of post harvest maturation in eight spring varieties of malting barley registered in the Czech Republic. Germination parameters (energy, rate, index, average time and homogeneity of germination) were monitored in the 3rd, 6th, 9th, and 12th week. The obtained data were related to the phonological phases and course of weather for the period of 2005- 2008. The studied parameters of germination were mostly affected by a locality (from 20 % to 60 %) and less significantly by year (14 %-30 %). The variety affected parameters of germination maximally from 15 %. Significant inter-variety differences in the length and intensity of post-harvest maturation were found. Calgary was the variety with the longest level of post-harvest maturation in the studied set of eight varieties and the variety Diplom had the shortest post harvest maturation. It was confirmed that the length and intensity of post harvest maturation was affected jointly by average rainfall and temperatures.Study was focused on the evaluation of the course of post harvest maturation in eight spring varieties of malting barley registered in the Czech Republic.
