There are three strategies of potato genotype storage: as microtubers, in vitro plantlets under slow-growth conditions and shoot tips conserved in liquid nitrogen. Microtubers are obtained from cultures grown on the medium enriched with 80 g·dm⁻³ sucrose, and after harvest the storage period is counted down. The slow-growth is obtained by lowering the temperature (to 10ºC) and irradiance and by adding the growth inhibitors (phytohormones and osmoticum). For shoot tips storage, the droplet technique is used: the shoot-tips are placed on aluminium foil in a cryoprotectant droplet and then they are submerged in liquid nitrogen. In this work, all these techniques were discussed, especially the in vitro genotype bank in Bonin.
