Identification of SNP markers associated with yield in winter oilseed rape (Brassica napus L.) hybrids.
Article in Journal of applied genetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Winter oilseed rape (Brassica napus), a crucial crop in temperate regions, is a key contributor to global vegetable oil production and an essential component of crop rotations due to its ability to improve soil structure and fertility. Enhancing its yield is vital for meeting the increasing demand for sustainable oil production, supporting food security, and optimizing biofuel production, while also ensuring the economic viability of agricultural systems in colder climates. The aim of the research was to determine association between SNP molecular markers and rapeseed yield. The plant material for this study consisted of 276 oilseed rape hybrids. The experiment was conducted in four localities: Borowo, Kończewice, Małyszyn, and Strzelce. The mean yield values ranged from 0.07 kg (for hybrid EH_20212 in Małyszyn) to 9.10 kg (for hybrid EH_20410 in Kończewice). The genotype matrix for 276 hybrids was constructed using marker data from the parental genotypes of inbred individuals (maternal and paternal lines). The matrix was coded as {- 1, 0, 1}, assuming an additive effect of the alleles. A total of 13,116 SNP markers were identified. For association mapping, 12,581 polymorphic markers were used. The results of the observation of the yield and sequencing were used for association mapping, which ultimately resulted in the selection of twenty-six molecular markers important (LOD > 5.0) simultaneously in all four localities.
