Seed potato (Solanum tuberosum) production systems in India: A chronological outlook

Abstract

Seed is a major and important input in potato (Solanum tuberosum L.) cultivation. On account of vegetative propagation, the requirement of seed potatoes (tubers) is voluminous and accounts for 40–50% to the total cost of production. Potato productivity in India is low in comparison to developed countries due to the non-availability of quality seed in required amounts. Seed potato production through micro-propagation (tissue culture) techniques can overcome the problems associated with the conventional multiplication system. The everlasting shortage of seed potatoes in most of the potato growing countries can be solved through hi-tech seed production system including micro-propagation and aeroponic techniques. Besides, rapid multiplication, production of disease-free mother stocks under controlled conditions followed by reduced number of field exposures as compared to conventional multiplication system, is an added advantage of seed potato production in these techniques. For expanding quality seeds, the entire seed production systems framework needs to be reviewed. The present review will be an endeavour to outline the historical background of seed potato production, issues and challenges, supply frameworks and policy implications in India.
