Abstract
With the view of optimization of production of disease free seed tubers of Solanum tuberosum L., the in vitro method which permits synchronous tuberization has been attempted with manipulated physicochemical parameters . Irrespective of PGRs, the highest shoot length was observed at 1.50 mg/ L in both apical and nodal segments showed the higher shoot length. The trend remained same for the PGRs in combination also. Regarding the various parameters, sucrose concentration, 8%, photoperiod, 18 hrs and temperature, 25 °C seemed to show the highest number of tubers.
