An efficient in vitro shoot multiplication has been standardized for propagating G. umbellata, an important dye yielding plant.
More than 6 shoots/node were produced in MS medium supplemented with 2 mg/l BA.
High percentage (90%) of field establishment rate were obtained in plantlets from NAA.
This method can be used for the conservation and rapid commercial propagation of high dye yielding plants of G. umbellata.
