| Molecular characterization using RAPD analysis was carried out in eight cut flowers and two pot plant cultivars of chrysanthemum. Three of them (`Refocus¿, `Red Reagan¿, and `Sheena Select¿) were established in vitro and the occurrence of somaclonal variation was studied using the same molecular technique. Two induction media (MS + 0.1 mg/l NAA + 0.1 mg/l BA, and MS + 2.0 mg/l IAA + 0.5 mg/l Kinetin), and two proliferation media (MS + 0.1 mg/l NAA + 0.2 mg/l BA, and MS + 4.0 mg/l IAA + 2.0 mg/l Kinetin) were employed in order to evaluate the effect of the medium composition in the shoots¿ stability. Likewise, the effect of the culture age was considered in assessing genetic stability. Monthly subcultures were carried out, identifying the origin and history of the shoots, throughout a nine-month proliferation period followed by acclimatization. Molecular markers were obtained in every subculture cycle and from the acclimatized plants. Only one shoot from the 7th subculture of the cultivar `Refocus¿ showed a different band pattern. The use of RAPD for chrysanthemum cultivar characterization and somaclonal variation detection is discussed. | |
