Here is discussed the number and nature of coconut accessions presently conserved in the National Coconut Gene bank of Vietnam, located in Dong Go Experimental Research centre in Ben Tré province. Pictures of some of the varieties conserved in the Genebank can be seen here.
As of January 2016, only 31 coconut accessions are presently registered in the CGRD (International Coconut Genetic Resources Database) for the National Gene Bank of Vietnam in Dong Go. IOOP provided a new list showing that the data presently available in CGRD is incomplete and that the collecting work was continued. Now the collection gathers 51 accessions (so 64% more) as shown in Table 1.
Such a similar situation may be found in many other countries; So the global number of coconut accessions collected by COGENT member countries is probably strongly underestimated. This number is very probably at least 25% more that what is presently registered in the CGRD database.
Notes:
- What is called in this list 'Guinea Green Dwarf', originally 'Equatorial Guinea Green Dwarf' was renamed by Côte d'Ivoire (collecting country) as 'Brazilian Green Dwarf population Equatorial Guinea', because there is historical évidence that this variety was introduced recently from Brazil.
- What is called 'Ghana Yellow Dwarf' is this list was renamed as 'Malayan Yellow Dwarf population Ghana by Côte d'Ivoire (collecting country).
- 'King Coconut' status would need to be reviewed. This Sri Lanka variety was classified as 'Semi-Tall'.
- Table 2 (at the end of this post) gives the list of the 31 accessions presently registered in the CGRD database as of January 2016.

MYD was replanted in 2006, as rejuvenation, but up to now most of the Tall varieties were not rejuvenated except the San Ramon Tall from the Philippines. San Ramon Tall was rejuvenated in 2005 by controlled pollination with bagging. No information yet about the number of female and male parent used for this rejuvenation.
