The development of new methods of seed production is then necessary to increase the availability of good quality seeds. The results concerning potato seed production in hydroponic systems indicate that this technique can be an alternative to the conventional production methods. The objective of this study was to evaluate the efficiency of hydroponic systems for pre-basic seed potato production.  aHydroponics  aPotatoes  aSeedling production  aBatata  aCultivo Hidropônico  aProdução  aSemente  aSolanum Tuberosum  aCultivos hidropónicos  aPatatas  aProducción de plántulas1 aMEDEIROS, C.
