ROLE OF IN VITRO MICRO TUBERS IN PRODUCTION OF POTATO
Rajendra Singh*
ABSTRACT Potato (Solanum tuberosum L.) is a globally important crop, providing a significant portion of the world's dietary calories. The traditional method of potato propagation through seed tubers has limitations in terms of disease transmission, limited availability, and slow multiplication rates. In vitro induction of micro tubers has emerged as a promising technique for potato production, offering numerous advantages over conventional methods. This review paper explores the role of in vitro induction of micro tubers in the production of potato, focusing on the various aspects of the process, including explant selection, culture media, growth regulators, and acclimatization. The use of in vitro induction of micro tubers not only provides a rapid and efficient means of potato multiplication but also allows for the production of disease free planting material, genetic improvement, and conservation of rare varieties. However, challenges such as genetic stability, cost effectiveness, and scaling up production need to be addressed to fully harness the potential of this technique. Six potato varieties including Kufri Jyoti, Kufri Megha, Kufri Giriraj, Kufri Girdhari, Kufri Himalini and Kufri Himsona were evaluated for their responses to in vitro propagation and tuberization. Rooting efficiency was good for all the varieties except Kufri Megha. No difference was observed among all the varieties and Kufri Jyoti in terms of the total micro-tuber number and weight except Kufri Megha, which recorded lowest yield. The present study clearly shows that different cultivars respond differently towards tissue culture conditions. Keywords: In Vitro, Meristem culture, Cultivar, MS Media, Shoot Length.
