Abstract: Wolf trees are the individuals, which grow faster than the surrounding trees, have a larger crown and other tree parameters, and utilize a larger growing space, thus reducing stand timber volume (Beck 2004, Makrickiene et al 2016). Such trees are usually undesired in the stands and are removed during the first thinnings, what makes their early recognition important for the forest management planing. Our study was aimed to to analyze the differences between the wolf trees’ and regular trees’ seed progenies from the beginning of their development. The seeds for the progenies research were collected from 8 mature wolf trees in naturally-born gene conservation stand in Kurtuvenai. The seeds for the control were taken from the officially selected seed trees from the same stand. The seeds were sown into the plastic containers, wolf trees and regular trees separately. The parameters of the seedlings were assessed in the beginning and in the end of every growth period. The results of our research revealed statistically significant differences in progeny size, form, phenology and stability. Progeny of wolf trees tended to inherit the wolf trees‘ form. Moreover, the difference between the progeny of the wolf trees and regular trees could be clearly visible already from the second growth period, what makes the early recognition of the wolf trees possible
