In vitro microtuberization in potato (Solanum tuberosum L.) cultivars.

Mechanism of microtuberization in three elite cultivars kufri badhsha (KB), kufri chandramukhi (KCM) and kufri jawahar (KJ) of potato was studied. Sprouts of all the three cultivars were used to obtain in vitro shoot cultures. MS medium supplemented with chlorocholine chloride was found to be most suitable for all the cultivars. Maximum tuberization was obtained under incubation conditions of continuous darkness at 20 degrees +/- 1 degrees C. The highest number of micro-tubers per plant basis was produced under continuous darkness and KCM recorded the highest yield of micro-tubers and was found significantly superior to KJ and KB.
