The Old Olomanu coconut Seed Garden and Genebank

The Olomanu Seed garden, located in the West part of Upolu island, is the place where coconut germplasm was conserved and where hybrid seednuts were produced. In the years 2010, it was turned to a Juvenile Rehabilitation Centre, under the Samoan Ministry of Police and Prisons and with no more link to the Ministry of Agriculture. Most of the accessions of the coconut gene bank have been cut off few years ago.

The following picture was taken during the harvest of Niu Afa palms at Olomanu.



According to the following map (click to enlarge), the varieties that were in the genebank are Rennell Tall (183 palms - P1), Samatau Tall (3 palms – P2), Niu Vai Tall (178 palms – P3), Niu Afa Tall (210 palms – P4), Niu Lea Tall (55 palms – P5), Niu Kogau and Niu Lea (7 palms-P6i), Samoa Local Tall (144 palms – P6ii), Natural Hybrids (82 palms- P6iii), Samoan Local (112 palms – P7), Niu Ati red dwarf (5 palms – P8) and Genetic Trial mixed with different varieties (282 palms – P9).

It appeared that the total number of living palms for Niu Afa was lower than 210 palms. A counting duirng the month of March 2010 gave 178 living palms. We selected visually 52 palms (29%) from the Niu Afa variety, preferring the palms producing large and long fruits. Finally seednuts were harvested only on 46 palms due to lack of fruits at the good stage for 6 palms.
