SNP profiling of Elaeis oleifera (H.B.K) Cortes germplasm in Ucayali, Peru using Genotyping-by-Sequencing (GBS).
Article in BMC research notes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesElaeis oleifera, commonly known as the American oil palm, plays a crucial role in the agricultural economies of Central and South America due to its unique oil characteristics and resistance to certain diseases. Despite its importance, limited available genetic information has hindered the effective utilization of this species in breeding programs aimed at improving oil yield and disease resistance. This study employed Genotyping-by-Sequencing (GBS) to profile polymorphisms within Elaeis oleifera populations, the unique germplasm bank for Peru, located in Ucayali, Peru, aiming to characterize the gene pool. DATA DESCRIPTION: The GBS analysis successfully identified 22,703 informative single-nucleotide polymorphisms (SNPs) across the twelve-year-old plant genomes (n = 42). Observed heterozygosity (Ho = 0.3086) and expected heterozygosity index (He = 0.3385) were quantified. The fixation index (Fst = 0.0048) indicated low genetic differentiation within the germplasm. However, the presence of two genetic clusters (C_1 and C_2) distributed homogenously within the studied population has been detected; the origin of these clusters could be mainly associated with the initial management of the germplasm nucleus within Peru. The extensive SNP dataset provides a comprehensive genetic map that is invaluable for the conservation and enhancement of Elaeis oleifera in our region.
