In the central Podravina seed region (Croatia), phenotypic selection of pedunculate oak (Quercus robur L.) was made and an experimental clone seed orchard with 40 clones was founded. During 1992, a test consisting of 21 half-sib progenies was established. The progeny trial involved the families from the selected mother trees included in the clonal seed orchards and belonging to the central Drava River seed region, with two population (Donji Miholjac and Slatina). Total heights were measured at the plantation age of 2 + 3,2 + 4,2 + 6 and 2 + 7 years. An estimation of genetic parameters (heritability and genetic gain) was made for in total 21 half-sib prognies, as well as separately for half-sib progenies from each population.
