Coconut Palms from Papua New Guinea: List of accessions recorded in the COGENT CGRD Database

By R. Bourdeix, 2019, in construction

We checked the number of accessions available in the CGRD, versus 2012 (in Dr Roland Bourdeix computer) and versus 2019 (on COGENT website). In both case we found 57 data. In September 2019, we asked the COGENT coordinator if any change was done regardin PNG data during the last years, but he had no idea.

Hereunder is a list of the 57 accessions. We checked that the field: " DATE OF LAST COUNTING" remains empty for all of them. That means that we now the number of palms that was planted but we dont know the number of palm that are remaining alive in 2019. It seems that a partial inventory was conducted in 2013 following the visit of Dr R. Bourdeix, but the data was never computeriezd.

This list includes all the 57 accessions registered in the database; anyway, some of these accessions had a 0 value for the accession size, meaning that: they were rejuvenated and cut; or lost; or the genebank never provided the data about accession size.

As shown in caption, the list of accessions was made more comprehensive by adding some criteria and analysis of the rarity of the germplasm and the quality of the data provided. This will help both users, to better understand germplasm conservation, and genebanks for improving the data available in the Coconut Genetic Resources Database.

Caption of the list

DP	Date (year) of planting
U	Uniqueness Number of accessions that, in the CGRD database, are conserving a specific population of coconut palms (cultivar+population).	For instance, the *Malayan Yellow Dwarf* is conserved as 34 accessions scattered in many genebanks; the *Thailand Brown Dwarf* is conserved by only one accession in Thailand.
DLC	Date of last counting/inventory
NBA	Number of alive palms.	Is there is no date of inventory, or if this inventory was conducted several years ago, we do not know if these palms are still alive.
	Population where the date of last inventory is missing or more than 10 years-old, or the number of living palms is unknown: the number of palm remaining alive in the field is uncertain and must be updated	543 accessions do not have a date of the last inventory; for 440, the inventory dates back more than 10 years old. For 153 accessions, the number of living palms is missing.
	Population highly endangered, conserved by only one accession and planted more than 24 years ago or for which the planting date is missing. Data must be updated and decision must be taken rapidly to regenerate it or to loss it.	607 populations are conserved in one genebank only, of which at least 255 were planted 25 years ago or later, and of which 39 have no recorded date of planting.
	Population highly endangered, conserved by only one accession and that should be regenerated in the 5 coming years	607 populations are conserved in one genebank only, of which 75 are aged from 20 to 25 years.
	Population with a number of living palm far under the standard (less than 40 living palms)	536 accessions have only between 1 and 39 living palms according to the last inventory.cc
PAS	Completion rate (%) of the descriptors of the passport section (in orange color when the completion rate is low as less than 40%)	Average completion rate is 57%. 424 accessions among 1680 have a completion rate of less than 40%.
CHAR	Completion rate (%) of the descriptors for the field characterization (in light orange color when the completion rate is low as less than 10%)	Average completion rate is 32%. 687 accessions among 1680 have a completion rate of less than 10%.
