Résumé

To establish an improved protocol for the cryopreservation of banana (Musa spp.), a fast-freeze/fast-thaw method was applied and compared with three existing cryogenic procedures: simple freezing, vitrification of proliferating meristems and vitrification of individual meristems. The average post-thaw shoot regeneration of the fast-freeze/fast-thaw protocol was 51.8% and was superior to the existing protocols which were 12.5, 39.2 and 42.8%, respectively. Other factors such as time and ease of operation were considered for each method. It was found that the fast-freeze/fast-thaw technique was the best of the four methods tested for the cryopreservation of in vitro banana meristems in the genotype Robusta (AAA).
