摘要

Potato is grown as world's major non-cereal food crop, in more than 148 countries in a wide variety of soils and climates and is surpassed by only wheat, rice and maize in total production. Potato has been identified as an important food crop to fighthunger and poverty in many parts of the world (FAO, 2008). It is an input intensive crop with its seed alone accounting for 40-50 per cent of the total cost of cultivation, making quality disease free seed a vital input for obtaining higher yields (Singh and Rana, 2013). In India, production of good quality seed production of potato is difficult because of the high vector pressure during the crop season in sub-tropical plains. As a result, cost of seed potato production reaches very high, forcing manypotato farmers to use locally grown seed despite severe yield losses (Kumar et ah, 2011). Hi-tech seed production systems have evolved and are used to boost conventional seed potato production and accelerate the multiplication process. In these systems propagation is carried out under controlled facilities like tissue culture labs, net houses and aeroponic systems. These tubers produced on microplants under insect proof net house and /or aeroponic units are reffered to as the minitubers, and are furthermultiplied as early seed generations under insect proof nethouses. This strategy has been rapidly adapted by the farmers to multiply their own seed in a disease-free state over a longer period. One of the main concerns among potato mini-tuber producers is the lack of information on specific horticultural management recommendations for its multiplication, since these practices are somewhat different from commercial potato production.
