CRYOCONSERVATION OF POTATO BREEDING CULTIVARS AT VIR

Cryopreservation of 20 potato breading cultivars was carried out using an original modification of the DV-Biotech droplet vitrification method. The post-cryogenic regeneration frequency of the apical buds was significantly (p <0.05) higher than the axillary buds of microplants. A significant effect of the genotype on the level of post-cryogenic regeneration was registered.
