Cryopreservation of Shoot Tips and Pollen of Potato

Cryopreservation is a frequently used method of long-term storage of potato meristems and pollen in liquid nitrogen (LN) in temperature of -196°C. This technique allows for theoretically unlimited storage of potato material. The most popular method of potato shoot tips preservation is cryopreservation by the solidification of liquids without crystallization (vitrification).The best method of pollen conservation is its direct immersion in LN. The successful regeneration after vitrification is genotype-dependent, which require optimization of protocol.
