“…Our study clearly confirmed the additive genetic determinants of fatty acid proportions in our E. guineensis cross, as the mean values of LM2T x DA10D progeny were the mean values of their parents, except for C18:2, which showed a non-additive genetic determinism, with LM2T appearing dominant over DA10D, consistent with Hardon [7].…”

We searched for quantitative trait loci (QTL) associated with the palm oil fatty acid composition of mature fruits of the oil palm E. guineensis Jacq. in comparison with its wild relative E. oleifera (H.B.K) Cortés. The oil palm cross LM2T x DA10D between two heterozygous parents was considered in our experiment as an intraspecific representative of E. guineensis. Its QTLs were compared to QTLs published for the same traits in an interspecific Elaeis pseudo-backcross used as an indirect representative of E. oleifera. Few correlations were found in E. guineensis between pulp fatty acid proportions and yield traits, allowing for the rather independent selection of both types of traits. Sixteen QTLs affecting palm oil fatty acid proportions and iodine value were identified in oil palm. The phenotypic variation explained by the detected QTLs was low to medium in E. guineensis, ranging between 10% and 36%. The explained cumulative variation was 29% for palmitic acid C16:0 (one QTL), 68% for stearic acid C18:0 (two QTLs), 50% for oleic acid C18:1 (three QTLs), 25% for linoleic acid C18:2 (one QTL), and 40% (two QTLs) for the iodine value. Good marker co-linearity was observed between the intraspecific and interspecific Simple Sequence Repeat (SSR) linkage maps. Specific QTL regions for several traits were found in each mapping population. Our comparative QTL results in both E. guineensis and interspecific materials strongly suggest that, apart from two common QTL zones, there are two specific QTL regions with major effects, which might be one in E. guineensis, the other in E. oleifera, which are independent of each other and harbor QTLs for several traits, indicating either pleiotropic effects or linkage. Using QTL maps connected by highly transferable SSR markers, our study established a good basis to decipher in the future such hypothesis at the Elaeis genus level.

“…An interspecific cross E. oleifera × E. guineensis shows mean values for fatty acid proportions which are intermediate between the mean values of its E. oleifera and E. guineensis parents (Hardon 1969;Macfarlane et al 1975;Meunier and Boutin 1975;Opute and Obasola 1979;Tan et al 1985). This is in accordance with the codominance theory for genes involved in palm oil biosynthesis and their alleles inherited from each Elaeis parent (Hardon 1969;Ong et al 1981). Surprisingly, the proportion of oleic acid of the interspecific hybrid parent SA65T was quite similar to the one of its E. oleifera parent of the Brazilian Coari origin (Table 1).…”

“…Its outer pulp (mesocarp) contains the (red) palm oil, and its kernel (endosperm) contains the kernel oil, minor oil similar to the coconut oil. The species E. oleifera has a very low yield in palm oil compared to commercial oil palm varieties (Tan et al 1985), but it has several desirable agronomic characteristics: Elaeis oleifera presents a slow growth of the stem (Hardon 1969), shows resistance to the bud rot disease in South America (Meunier 1991), and a more edible palm oil in its fatty acid composition and concentrations of metabolites (carotenes, tocoferols, and tocotrienols) also important for the phytopharmaceutical industry (Choo et al 1997). Genetic advantageous features from both Elaeis species can be combined by interspecific hybridization for creating more performing oil palm varieties (Ong et al 1981).…”

“…For a single QTL, quite small minimum population sizes at each generation (often less than ten, depending on the position of the markers relative to the QTL) are sufficient to ensure that at least one individual has the required genotype; with more than one QTL, numbers are larger. Such a programme would be quite feasible with oil palm, and the approach might be useful to incorporate novel characteristics from the American oil palm Elaeis oleifera (Hardon 1969) into a high yielding E. guineensis background. However, a number of factors can influence the effectiveness of marker assisted introgression.…”

Quantitative trait loci for yield components in oil palm (Elaeis guineensis Jacq.)

The development of an oil palm RFLP marker map has enabled marker-based QTL mapping studies to be undertaken. Information from 153 RFLP markers was used in combination with phenotypic data from an F 2 population to estimate the position and effects of quantitative trait loci (QTLs) for traits including yield of fruit and its components and measures of vegetative growth. The mapping population consisted of 84 palms segregating for the major gene influencing shell thickness. Marker data were analysed to produce a linkage map consisting of 22 linkage groups. The QTL mapping analysis was carried out by interval mapping and single-marker analysis for the unlinked markers; significance thresholds were generated by permutation. Using both single-marker and interval-mapping analysis significant marker associated QTL effects were found for 11 of the 13 traits analysed. The results of interval-mapping analysis of fruit weight, petiole cross section and rachis length, and ratios of shell:fruit, mesocarp:fruit and kernel:fruit indicated significant (P<0.05) QTLs at the genome-wide threshold. The putative QTLs were associated with between 8.2% and 44.0% of the phenotypic variation, with an average of 27% for the single-marker analysis and 19% for the interval-mapping analysis. The higher percentage of phenotypic variation explained in the single-marker analysis, when compared to the interval-mapping analysis, is likely to be due to the lower stringency associated with the single-marker analysis. Large dominance deviations were associated with a sizeable proportion of the putative QTLs. The ultimate objective of mapping QTLs in commercial populations is to utilise novel breeding strategies such as marker-assisted selection (MAS). The potential impact of MAS in oil palm breeding programmes is discussed.
