The surprising diversity of Pineapples (Ananas comosus).
The Active Pineapple Germplasm Bank (Pineapple AGB) of Embrapa Cassava & Fruits (Embrapa/ CNPMF) has more than 700 accessions under field conditions. As backups, there are copies kept in a greenhouse, with one or two plants per accession, cultivated in plastic pots with commercial substrate. An in vitro gene bank was established in 2003, and during the past few years, several studies have been carried out to improve the in vitro conservation protocol. Currently, about 60% of the AGB’s accessions are preserved by this protocol. Another conservation strategy used is cryopreservation of shoot tips and pollen grains, with well-defined methods. One of the most significant advances in the pineapple germplasm conservation has been the implementation of a quality control system, which enabled to define standard operation procedures (SOP) towards a more efficient and safer germplasm conservation.
