Genetic Variation Of Kelampayan (Neolamarckia Cadamba) Trees For Planted Forest Development In Sarawak
Neolamarckia cadamba is now a commercially important plantation species, and is seen slowly but surely replacing other exotic species. Therefore, it is crucial that we have the tools to determine the genetic variation of N. cadamba that occurs in Sarawak, both for natural and planted populations....

| description | Neolamarckia cadamba is now a commercially important plantation species, and is seen
slowly but surely replacing other exotic species. Therefore, it is crucial that we have
the tools to determine the genetic variation of N. cadamba that occurs in Sarawak, both
for natural and planted populations. The objective of this study is to assess the
genetic variation of N. cadamba from different areas in Sarawak by random amplified
polymorphic DNA (RAPD) markers. To date, leaf samples from a total of 162
individual trees have been collected from five populations, namely: Matang, Sabal
and Simunjan, Bintulu, Miri and Sibu. Total genomic DNA is isolated from the silicagel‐
preserved leaf samples, and subsequently the isolated DNA is analysed using
RAPD technique. The RAPD marker detects DNA variations that result in the loss or
gain of DNA fragments at a particular location in the Kelampayan genome. These
variations will help us determine genetic relatedness and diversity between different
Kelampayan populations. The results of this study will provide a foundation in the
selection of plus trees, establishment of forest seed production areas, and
subsequently production of high quality seedlings for plantations with all the
desirable characteristics in term of growth rate, bole form, wood density and disease
resistance. |
