Abstract
The occurrence of genetic instability in regenerated chrysanthemum plants from encapsulation-dehydration cryopreservation protocol has been detected using RAPD and AFLP markers (1). Beside, previous analyses have indicated that some morphological variations, mainly related to the leave shape, can be observed in regenerated plants, although no correlation could be established between those samples with genetic variation and morphological alterations. In this study, 30 acclimatized plants derived from different steps of an encapsulation-dehydration cryopreservation protocol have been analyzed to assess their genetic (using RAPD markers) and epigenetic stability (through CRED-RA markers). Different morphological parameters (18) have been measured. The three different approaches have been compared in order to establish the relationship between (epi)-genetic changes and morphological characteristics.
