“…The application of DNA marker technology in the NIFOR oil palm breeding programme would not only reduce the breeding duration but ensure greater precision in the production of planting materials [20] [21]. Molecular markers offer great scope for assessing genetic diversity and relationships among natural or breeding populations because they are impervious to environmental conditions and are detectable in all stages of plant growth and development [22].…”

The genetic diversity among 15 NIFOR breeding parents was assessed using 10 microsatellite markers. A high genetic diversity was observed with a total of 64 alleles including 23 rare alleles or alleles at frequencies less than 0.05. The NIFOR tenera parents recorded the highest number of rare alleles. The average observed heterozygosity and mean gene diversity across all parental groups were 0.6889 and 0.7029, respectively. Higher genetic diversity was detected among the NIFOR dura and tenera parents compared to that of the Deli dura parents in absolute terms. Analysis of molecular variance (AMOVA) showed that 87% of the total variation (p < 0.001) observed was due to differences among parents. Rogers' genetic distance ranged from 0.2988 to 0.8000 (mean = 0.5570). The dendrogram constructed on the basis of Rogers' genetic distance clustered the parents in three groups. They generally clustered in heterotic manner rather than by geographic origins. The groupings obtained through PCoA confirmed the results obtained by cluster analysis. The results obtained are strong assets for NIFOR breeding programme.

“…Molecular markers are neutral, not environment dependent, and detectable at all plant growth stage (Mohan et al, 1997). They provide an opportunity to characterize genotypes and to assess plant genetic diversity more precisely than agro-morphological markers (Brumlop & Finckh, 2011).…”

Nine SSR markers were used to study the genetic relationships among 26 elite oil palm materials from Nigeria and Malaysia. The Nigerian elite materials comprised 15 Nigerian Institute for Oil Palm Research (NIFOR) oil palm parental genotypes. The 11 Malaysian genotypes included 2 dura and 2 pisifera advanced breeding lines, 3 palms from natural populations of Nigeria, and 2 from each of the Angola, and Madagascar natural oil palm collections maintained at the Malaysian Palm Oil Board (MPOB). The results revealed a high percentage of polymorphic loci (83.3%) in the entire materials with average polymorphic information content (PIC) of 0.7325. Two SSR markers showed relatively high PIC namely sMg00016 and sMg00179 (0.8018 and 0.8509, respectively). The mean number of alleles varied from 1.333 in Madagascar germplasm material to 4.889 in NIFOR tenera materials (mean = 2.958). The observed heterozygosity varied from 0.167 in Madagascar material to 0.778 in Nigeria germplasm materials (mean = 0.575) and the expected heterozygosity from 0.153 to 0.643. The various oil palm provenances showed significant genetic differentiation (F ST = 0.177, P = 0.001) indicating the existence of a genetic structure among the materials used. UPGMA analysis based on Rogers' dissimilarity coefficient matrix displayed two main clusters, one separating Madagascar accessions from the rest. PCoA showed that the NIFOR breeding parents clustered closely with MPOB's Nigeria and Angola-derived materials suggesting a common origin of mainland genotypes. The high genetic diversity observed among the MPOB's germplasm materials highlights the need for proper characterization of entire NIFOR oil palm germplasm with SSR markers to facilitate effective utilization in the breeding programme.

“…This method also uses arbitrary primers and does not require prior genomic information. AFLPs can potentially identify a large number of loci, and is commonly used to map a segregating population (Gallego et al, 2005, Harry et al, 1998, Mohan et al, 1997and Vos et al, 1995. Although…”

“…Applications for Molecular Markers CAE-SSCP molecular markers have several applications such as, population/conservation studies, marker assisted selection (MAS), establishing synteny/comparative genomic mapping, creating or extending linkage maps, and identifying candidate genes (Baba et al, 2003;Kuhn et al, 2003;Liewlaksanneeyanawin et al, 2004;Mohan et al, 1997).…”

“…This would make it less difficult to create linkage maps for species that have little or no information about their genome, and aid in the identification of candidate genes (Acarkan et al, 2000;Devos and Gale 2000;Grant et al, 2000;Kuhn et al, 2003;Paterson et al, 2000;Salse et al, 2002;Yan et al, 2004 (Dirlewanger et al, 2004;Mohan et al, 1997;Steele et al, 2006). Using molecular markers for MAS can propose a quicker and more effective way for selecting the best cultivars within a population (Dirlewanger et al, 2004;Fazio et al, 2003;Liewlaksanneeyanaein et al, 2004;Mohan et al, 1997). One major advantage to this technique is that the plant can be tested with molecular markers for the preferred traits at any time during its life, thus saving years of waiting for the plant to reveal certain characteristics in the field (Dirlewanger et al, 2004 andMohan et al, 1997).…”
