Given the current climate context, the main objective of this study was to identify genotypes tolerant to water stress in true potato seed populations. The research was initiated by inoculating of true potato seeds on culture medium, regenerating viable plantlets and testing their tolerance to in vitro induced water stress. Three from nine tested genotypes obtained the best results in terms of tolerance to water stress induced in vitro. ELISA testing revealed that the three genotypes (GIL 19-03-07, ZIL 19-02-43 and GIL 19-03-29) are virus-free. In vitro true seed derived plantlets owning a very high health status were transplanted, after acclimatization, in protected area in order to produce top quality, disease-free seed potato material. Several planting variants were used in terms of biological material used, number of plants/pot and location. After minitubers were harvested, it was analyzed how the planting variants influenced number, size and weight of the minitubers obtained in the protected area. This study aimed to obtain an alternative planting material with a high phytosanitary quality and drought tolerance, to supplement the seed potato required by the market.
