An Approach to Sustainable Management of Population Genetic Resources of Trees Ⅰ. Relevant Theoretical Analyses of the Information on Population Genetic Variation

Sustainable management of forestry has been becoming a central issue in recent years,while sustainable management of genetic resources is an important part. Information on population genetic variation plays a critical role in guiding sustainable management of genetic resources of tree species. Some relvant theories and their association with sustainable management were discussed in detail in this paper,including mating system,origination and formation of populations,spatial variation,population genetic structure,and the interaction between genotype and environment. Detection of these kinds of information was carried out by using selectively neutral molecular markers and adaptive quantitative traits. Comprehensive use of the information detected by both types of genetic markers can contribute to decision-making on conservation of genetic resources,on ideal size of population maintained and on appropriate management for utility in the future.
