Description Availability of disease-free quality seed material is the urgent need for improving potato productivity. In vitroplants of potato are the pure form of seed and are free from disease pest contamination. The present study was undertakenunder an insect-proof net house to evaluate the performance of microplants of two potato varieties (Kufri Pukhraj and KufriHimalini) at three different planting densities. The results of the experiment reveal that for getting the maximum numberand yield of mini-tubers from in vitro plantlets under soilless culture in insect-proof net house, we should increase plantingdensity to 66 plants per m2 (spacing of 15X10 cm). In a mini-tuber production scheme, it is always important to get yieldin terms of numbers in relation to the size. The multiplication rate in potato seed production is low (4-5 times), hence itis always desirable to increase the number of tubers produced at harvest even if some compromise has to be done withthe size of tubers. Since both the number and weight of minitubers obtained was higher at closer spacing, it is better toreduce the spacing to accommodate more plants resulting in the production of more number of tubers in the same area.
