Thirteen groups of somaclones (seven in Maran and six in Rio-de-Janeiro) were evaluated using Random Amplified Polymorphic DNA (RAPD). RAPD analysis using twelve selected primers produced 129 amplicons, 44 were polymorphic with an average of polymorphic bands / primer and a polymorphism percentage of . The dendrograms generated based on RAPD profiles grouped the somaclones into two separate clusters. RAPD marker system showed that somaclones derived from cultivar Maran exhibited more variability than Rio-de-Janeiro. | Variability analysis in ginger Zingiber officinale Rosc. somaclones using RAPD marker system
