Oil palm genetic material bank of Cameroon is interested and well distributed in a lot of oil palm improvement research and producer centers of tropical area of the world. Using the Next Generation Sequencing, we sequenced the genome of 169 wild accessions, 25F1 tested progenies, 09 advanced parents and 01 oleifera individual. The assemble genome sequence contained 11,578 scaffolds for a total genome length candidates of 10.034362 Mb. A total of 21,302 nucleotide polymorphism or genetic variations were discovered, from which 20,959 single nucleotide substitutions or SNPs and 343 insertions/deletions or Indels were discovered, indicating the evidence of great diversity of nucleotides variants across the studied genome. The frequency of the single nucleotide substitution observed was 1 SNP in 471 bp. The number of transition point mutation events was more detected compare to the number of transversion, with the ratio of transition/transversion equal to 9.65. The investigation on the genetic population structure determined the best suitable K value at 3, referring the number of the major subpopulations. In addition, the result revealed that most of the individual studied genomes were admixed. Our data provide useful and valuable oil palm resource material for accelerating oil palm genetic improvement breeding program progress.

Keywords: Genome-wide genetic diversity, NSG, polymorphic loci, population structure, admixture.
