| Abstract:
The genetic variability within and among Spanish populations of wild and orchard chestnut (Castanea sativa) was investigated. Buds of twelve populations originating from six different sites were analysed, distinguishing two domestication levels within each site, wild and orchard. Effective population size and adaptedness were evaluated using isoenzyme markers. Wild and orchard populations were characterized and the effects of handling the trees were identified. Naturalization events and their effects were also analysed. Isoenzyme analysis is shown to be a useful tool for establishing practical guidelines for the choice of stands for providing the basic material for the production of “selected” reproductive material. | |
