Study of the genetic stability of plant potatoes grown outside the living body after years of repeated cultivation using the technology of randomized reaction of DNA

Random Amplified Polymorphic DNA markers were used toevaluate the genetic stability of micro propagated plants of potato(Solanum tuberosum) var.Desiree .To achieve this genomic DNA wasextracted from the samples to comparison between the DNA of plantletmicro propagated through meristem culture and the DNA of the plantlets(7 samples) after sub culturing 16 times, beside the comparison within thesamples.Fifteen arbitrary primers were used to amplify DNA from the samples, toassess the genetic stability .All RAPD profiles from micro propagatedplants were mono morphic and similar to the DNA of the origin sample.no variation was detected within the micro propagated plants, this provethat potato plants used in this study were resistant to somaclanal variationand utilization of RAPD markers for the assessment of genetic stability.
