Preliminary assessment of genetic gain through the selection of different pedunculate oak populations in provenance test

The distribution of pedunculate oak in Bosnia and Herzegovina is important connecting the southern eastern provenances Balkan Peninsula with from Central Europe. However, due to over-exploitation, almost extinct Herzegovina. This research aims determine heredity production potential 28 Bosnian-Herzegovinian provenance test through genetic gain thickness height growth. results will be used selection best terms gain. For this research, root collar diameter plants tests were measured 2012, 2016 2020. was established 2009. It contains Heredity differential assessed using analysis variance. Possible if five one determined. for obtained data 2012 2020 low. indicate that height, would 7.62%, 9.98%. Results improvement 4.28%, 6.32%. by selecting their propagation, we can achieve a significant increase plant thickness, i.e., yield wood mass. As concerns juvenile material, it necessary continue systematic monitoring, actual age, when trees reach physiological maturity, annual value oscillations become uniform.
