Do not plant a coconut palm in a genebank
without knowing, recording and mapping at least its mother parent palm.
- On the oral recommendations of the owner of the plantation, or of the workers haversting the palms, as they generally know which are the best palms and which palms have special characteristics, such as for instance palms giving a thick and tasty coconut milk for food.
- On the visual characteristics of the palm, choosing preferably the palms that look healthy and bear a lot of fruits
- If possible on fruits characteristics, that can be evaluated under palms in the fields ; another simple way is to check the thickness of the husk by enfonçant in the husk the point of a knife. This will help to select fruits with thin husk.
- Do not choose the biggest and heaviest fruits, as there is a negative correlation between the number and the weight of fruits, as as choosing only the bigger fruits will result on a decrease of the yield of kernel per palm per year.
- Ask the gardener where he got the seedlings, and if possible locate and collect also the parent palm of this dwarf
- Ask the gardener if he/she already gives seednuts of this Dwarf palm to family or friends; and if so, try to locate where this progeny is planted.
- Make a deal with the gardener, proposing he will keep and germinate the seednuts. The seednuts with sprout of the same colour than the original palm will be paid three times the price of a normal coconut.
- Date of harvest
- Collecting number of the population
- Mother palm number
- Latitude of the mother palm
- Longitude of the mother palm
- Number of seednuts harvested per mother palm
Here is a view of a possible full design, 5 Tall populations plus a control, in a Fisher block design with 4 replications of 24 palms (4 rows of 6 palms), so a total of 96 palms per accession. All numbers of female parent palms are recorded in the map.
, avoid to use pollen mix (pollen of one father palm should be crossed separately with mother palm), and record the identity of both parents for each palm planted in the genebank, in a map and in a file.
