Using the micro-propagated potato shoots, originating from meristem culture was used to produce microtuber. Effect of different vessels and paclobutrazole were studied and results revealed that the size of culture vessels play important role for the microtuber production and among them 150 Erlenmeyer conical flask is most suitable. The varietal performance of Kufri Chipsona-1 found to better response in terms of obtaining maximum weight. The paclobutrazole effect on microtuberisation weight and size were non-significant, however the weight of microtuber were higher (0.110 gm) in the paclobutrazole treated treatment and corresponding size were reduced (0.487 cm) in paclobutrazole treatment. At the very same time its effect on number of microtuber were significant and it was maximum (4.7) in case of M2 treatment where paclobutrazole were absent and less/ reduced, number (3.4) in the paclobutrazole treatment.
