The paper presents the results of an analysis of morphometric characteristics of Nor- way spruce seedlings in the progeny tests in Bosnia and Herzegovina, localities: Drinić and Sre- brenica. Progeny tests were established by using seedlings originating from six natural popu- lations from Bosnia and Herzegovina. Seedling height, root collar and whorl distance from the ground, which represents seedling heights in 2011, 2012 and 2013 were measured. The results indicate statistically significant differences between the analyzed characteristics of the observed population. Especially interesting are the populations Potoci and Olovo, which showed the highest growth during the observed period in both progeny tests. The impact of the drought in 2013 can be seen in the progeny test in Srebrenica where height growth in 2013 was lower by more than 50% in comparison to 2012. The impact of drought in the progeny test in Drinić was not observed. The research provides the baseline when selecting the starting population, where the rapid growth of seedlings is set as the main goal
