Özet
The Mediterranean Basin is one of the major plant diversity centers in the northern hemisphere. The Eastern Mediterranean Basin is also a hotspot region of gene diversity for conifer species. In this study, Turkey's conifer seed orchards were investigated for their effective number of clones. The mean census number of clones (N) was estimated 33.12. The mean effective number of clones (N-c) was calculated as 27.59. The mean relative effective number of clones (N-r = N-c/N) was 0.827. The estimated proportional gene diversity was found 0.973, with a range from 0.922 to 0.983. Thus, considerable attention should be given to use nearly equal ramet numbers during seed orchard establishment and management operations. Threats such as climatic change, fire, disease and insects should be considered during seed orchards establishment. High number of populations from wide range of species should be sampled and seed orchards should be established locally depending on ecological requirements of species. This is also essential for sustainable management of forest genetic resources. Information both from phenotypic selection and molecular genetic analysis should be used to establish future seed orchards.
