Abstract

The aim of this study was to study the genotype response for in-vitro propagation of date palm (Phoenix dactylifera L.) and to ensure the genetic stability of plantlets produced by tissue culture via somatic embryogenesis through RAPD-PCR technique. To achieve this, three cultivars (Shamran, Halawy and Medjool) were used for callus induction. The nodular creamish-white callus was produced on Murashige and Skoog (1962) medium supplemented with 10 and 25 mg/l 2,4-D + BA (3 mg/l), 2-ip (1 mg/l) and activated charcoal (1.5 g/l). Somatic embryos were produced on MS medium with 0.1 mg/l BA in 30-40 days and they germinated into plantlets on the same medium. In RAPD-PCR of three cultivars, it was found that there was no variation between mother plant and their clones produced via somatic embryogenesis.
