Abstract

An Attempt to combine the superior traits of Elaeis oleifera and Elaeis guineensis have been done through an interspecific hybrid cross and followed by pseudo-backcross 1 (pBC1). Observation of vegetative morphology and bunch components are presented in this paper. Two populations of pBC1 E. oleifera from the Suriname and Brazil origin were planted in 1990, 1993, 1995, and 2005, and were intensively observed for vegetative morphological properties and bunch components in November 2016 to February 2018. The results showed that almost all the individuals of pBC1 grew upright such as E. guineensis, no longer growing horizontally like the wild E. oleifera and the interspecific hybrid populations. The datas showed that the Suriname population plant architecture are compact or smaller than the Brazilian origin including the height increment and the size of the stem, the frond architecture and its components. Similarly, the bunch components show that the pBC1 Brazil is slightly superior to Suriname pBC1.

Abstract

Oil palm (Elaeis guineensis) is currently the highest edible oil-producing plant in the world. E. oleifera is another species of oil palm that is not widely cultivated due to lower productivity. Oil extracted from E. guineensis has a balance ratio of saturated to unsaturated fatty acids level, while E. oleifera has a higher unsaturated fatty acids. Long chain saturated fatty acids are more harmful for human health than unsaturated fatty acids. Gene encoding β-ketoacyl ACP synthase II (KAS II, EC 2.3.1.179) was studied, as this enzyme is responsible for biosynthesis of unsaturated fatty acids. Observation and analysis were conducted for KAS II gene and fatty acids content of E. guineensis represented by DxP Lame, DxP Langkat and CMR78 samples, E. oleifera represented by Suriname origin, and two hybrids (E. guineensis x E. oleifera (Brazil and Suriname)). The results showed E. oleifera Suriname had the highest concentration of oleic acid, followed by E. guineensis (CMR78). KAS II gene sequences alignment showed some genetic variation within E. guineensis and hybrids, while the high level of variation found between E. guineensis and E. oleifera was considered caused by species difference.

Abstract

The oil palm breeding program for the species Elaeis guineensis and the backcross Elaeis oleifera is running slowly because oil palm is an annual plant. Therefore, it is necessary to have an alternative approach that can accelerate the oil palm breeding program. The SNP (single nucleotide polymorphism) genome-wide approach was then used to study the association between 18 phenotypes of bunch component in oil palm germplasm of E. oleifera from Suriname and Brazil Coari, some interspecific hybrids and some elite progeny of E. guineensis. The genotyping by sequencing (GBS) analysis produced a total of 459 million or approximately 798 thousand reads per sample and 3,252 SNPs were eligible for 456 genotypes. Using various association models, eleven normalized phenotypic data showed significant associations with 29 SNPs. Based on the annotations, 17 SNPs were related to genes wtih certain biological functions. Three SNPs were found to be at the exon of a gene, namely SNP4416, SNP349 and SNP3865, while the other 15 SNPs were at the intragenic to a gene. Four SNPs are common SNPs in phenotypes C16:0 and C18:1 as weel as in C20 0 and C20:1. This research shows the potential of SNPs that can be used as an alternative approach to E. oleifera backcross breeding, although further research is needed for validation purposes.
