Abstract
The cytogenetic study of Abies sibirica seed progenies in decline fir stands of West Sayan High Mountains was carried out. The chromosome and genome mutations, pathologies of mitotic cycle and cells with micronuclei were recorded with high frequency. The revealed irregularities might be a result of the long-term exposure to extreme environmental factors and they probably reflect the high level of West Sayan highland forest ecosystems decline.
