ABSTRACT: The ornamental camellia most widely cultivated is Camellia japonica L., having more than 30,000 cultivars described. In the gardens of manor houses in Galicia grow specimens of C. Japonica having more than one hundred years old, in most cases of unknown origin but sometimes ascribed to a specific cultivar by comparison to old drawings and descriptions found in ancient nursery catalogues. The correct identification of gene resources of C. Japonica is crucial for the management and preservation of the collections and gardens and has an important commercial interest, since there are several nurseries interested in the propagation of plant material of old specimens such as Galician cultivars. In Galicia, some camellia specimens of historic interest were characterized and catalogued, using morphobotanic descriptors. On the other hand, in the last years molecular techniques for the characterization of plant material have been optimized. In Camellia sinensis L., the microsatellite gene markers were able to identify and determine a specific cultivar, thus they could be useful for the differentiation of C. Japonica L. cultivars. The aim of the present work was to characterize 13 C. Japonica old specimens growing in Galicia by morphobotanic and microsatellite markers. |
