Different aspects of micropropagation through meristem culture for the production of virus indexed source plants, callus induction followed by subsequent plant regeneration, in vitro tuberization and field evaluation of the in vitro regenerated plants were studied on four commercial cultivars of potato (Solanum tuberosum L.) viz., Diamant, Cardinal, Shilbilati and Lalpakri. Rooted plantlets of four potato cultivars obtained directly through meristem culture and indirectly via callus phase were gradually acclimatized and successfully established in the field. Visual evaluation of the...
