    • A highly efficient in-vitro system of micropropagation of rose scented Geranium, Pelargonium graveolens L. Herit by a direct regeneration method to produce a large number of viable true to the type plants maintaining the genotype of an elite mother plant is provided. The process involves inoculating nodal explants on shoot regeneration and multiplication medium, transferring the multiple shots for further growth on medium for shoot growth, further transferring the shoot with sufficient growth to medium for rooting. The present invention also provides a process for the primary and secondary hardening of the in vitro generated plants with the efficient root regeneration system, which is hardened to give about 95% survival in the field conditions. The multiplication ratio achieved by the process is of the order of 1:12 -1:20, resulting in significantly low cost of production in relatively lesser time
