“…In relation to the countries and regions of higher diversity, MAIZURA et al (2006) found that the populations of Nigeria presented the higher average number of alleles per loci and the higher percentage of polymorphic loci, coinciding with the results of HAYATI et al (2002) that found the higher diversity in Cameroon and Nigeria. It is proposed that Nigeria is the center of diversity of African oil palm, which is also sustained in the fact that as the geographical distance increases, the indexes of diversity decrease.…”

“…The studies of PURBA et al (2000); MAIZURA et al (2006) and COCHARD et al (2009), that analyzed the genetic diversity of collections of African oil palm by AFLPs, RFLPs and microsatellites respectively, found that the 'Deli' germplasm constitute a differentiated group with scarce genetic diversity. MAIZURA et al (2006) estimates a loss of 36 alleles in the Deli dura in relation to natural populations ;and HAYATI et al (2004) found that the population 'Deli' did not present rare alleles or intermediate genetic frequencies.…”

“…The mean number of alleles (A o = 2.958) and effective number of alleles for the respective oil palm groupings (A e = 2.445) was relatively higher than the values (A o ≤ 2.0) reported using different marker techniques such as RFLP (Maizura et al, 2006) and isozymes (Hayati et al, 2004;Purba et al, 2000). SSRs have revealed more alleles than other marker techniques.…”

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.

“…Generally the information on diversity and population structure of E. oleifera germplasm is still limited [5][6][7] compared to the E. guineensis germplasm which has been well characterised using variety of molecular markers such as isozymes [8]; RFLPs [9], SSRs derived from expressed sequence tags [10], genomic based SSRs [11] and SNPs [12]. The present study aims to unravel the population structure of MPOB E. oleifera germplasm collections using the model-based method.…”

Elaeis oleifera serves as a source of genetic foundation in oil palm improvement programme, as it possess several interesting agronomic traits such as slow growth, higher oil unsaturation and disease resistance. Malaysian Palm Oil Board (MPOB) has developed a collection of simple sequence repeats (SSRs) from Elaeis oleifera genome (E. oleifera-gSSRs). A total of 21 polymoprhic SSR markers were evaluated in the attempt to assess the population structure of E. oleifera populations. The appropriate common ancestry (K) value was determined to be seven from the likelihood scores. The profile from STRUCTURE analysis indicates considerable sharing of genetic components among E. oleifera population with an exception for Population 01 from Columbia and Population 02 from Costa Rica. The present study provides information on population structure of MPOB E. oleifera collection via model-based method for germplasm conservation and utilisation in breeding programmes.
