Abstract:	There is a great need for research aimed at understanding drought tolerance and creating breeders of varieties with tolerance / resistance to water stress. The present study had as goal to establish an effective in vitro method for determination of hydric stress over potato (Solanum tuberosum L.) plantlets, from different varieties. It was used as osmotic stress agent the agar with different levels of concentrations applied in Murashige Skoog medium. Hydric stress in culture affected plantlet growth and the responses varied with genotype. Roclas variety was less affected than Christian and Rustic.
