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 3.66 polymorphic bands / primer and a polymorphism percentage of 34.10. 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. In group wise variability analysis using bulked DNA, the groups RC20 Gy and RSe10 Gy recorded higher variability from source parent cultivar. The variability exhibited in plant wise analysis using two selected primers was found very high (39%) as compared to group wise analysis (25%). The somaclone RC2Kr1031 of the callus regenerants and RSe1Kr1052 of the somatic embryo regenerants showed more variability exhibiting 59 and 53 per cent respectively from the source parent cultivar Rio-de-Janeiro.
