We aim to determine whether the genetic diversity in declining spruce stands was successfully transmitted to its self-seeded progeny.

We investigated three spruce stands from the Śląski and Żywiecki Beskid and one primeval forest from the Tatras, as a reference. We noticed a high level of gene diversity, allelic richness and an effective number of alleles in progeny of all stands, without differences between declining stands from the Beskids and the primeval forest. The gene diversity was similar in maternal trees and their offspring. Higher gene diversity and generally higher number of alleles were noticed in young generation of stands.
