Genetic Diversity of Black Pepper in Bangka Island Studied by Researchers

Strategic Insights -

Researchers from Universitas Bangka Belitung in Indonesia have conducted a study on the genetic diversity of black pepper plants in the Bangka Belitung Islands Province, a major centre of black pepper production in Indonesia. The study employed SSR markers to determine the genetic diversity and relationships of Bangka landrace black pepper. The research aimed to identify superior varieties of black pepper that can increase production in Indonesia, which has experienced a drop in black pepper production.

Key Takeaways:

  • The study used 8 black pepper genotypes: Lampung Daun Kecil (LDK), Nyelungkup, Petaling 1, Chunuk, Peremis, Balunijuk 1, Balunijuk 2, and Jerambah Gantung.
  • Seven SSR markers were employed in the study: Psol3, Psol6, Psol9, Psol10, Psol11, Psol17, and Psol19.
  • The genetic relationship of Bangka black pepper was analysed using the UPGMA method, revealing two main clusters of eight Bangka black pepper genotypes.
  • Cluster I consisted of the Peremis and Balunijuk 2 genotype, while Cluster II included the remaining six genotypes.
  • The structure population exhibited two subpopulations, with FST values of 0.30 and 0.61, respectively.
  • The results showed that 7 primers produced polymorphic (82.1%) and monomorphic (17.9%) bands on eight pepper genotypes.
  • The average Polymorphic Information Content (PIC) value was 0.32, categorized as medium.

Statistics:

  • 8 black pepper genotypes were used in the study.
  • 7 SSR markers were employed.
  • 2 main clusters of Bangka black pepper genotypes were identified.
  • FST values for the two subpopulations were 0.30 and 0.61, respectively.
  • 82.1% of bands were polymorphic, and 17.9% were monomorphic.
