Genome-wide association study and KASP marker development for flour color in winter wheat.
Article in Scientific reports, 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
Flour color influences the quality of end-use products of common wheat (Triticum aestivum L.). To analyze the genetic basis of flour color, the flour brightness (FL*), red-green level (Fa*), yellow-blue level (Fb*), and whiteness (W) of 341 winter wheat materials grown during the 2019-2020 years and 2020-2021 years in Emin and Qitai were measured. A genome-wide association study was conducted using a wheat 40 K breeding chip with the MLM model. The coefficient of variation and generalized heritability of wheat flour color traits ranged from 0.62% to 22.23% and 55.52% to 83.48%, respectively. There were strong correlations across the flour color traits. GWAS identified 20 significant and stable SNP markers distributed across 16 loci, including 1 for FL* located on chromosome 5D; 6 for Fa*, located on chromosomes 1 A, 5 A, 1B (2), 6B, and 4D; 6 for Fb*, located on chromosomes 2 A (2), 4 A, 4B, 6B, and 5D; and 3 for W, located on chromosomes 2 A, 4 A, and 5D. Two KASP markers were developed for Fa*, which exhibited good genotype and significant phenotypic differences among materials with different genotypes. Seven candidate genes that may affect flour color during grain development were screened, including TraesCS5D02G01340.1, TraesCS5D02G013100, and TraesCS5D02G014300.1 on the 5D chromosome may simultaneously influence W, FL*, and Fa*, TraesCS1B02G269100.1 and TraesCS1B02G269500.1 on the 1B chromosome may impact Fa*, while TraesCS4A02G307200 and TraesCS6B02G034100.1 on the 4 A and 6B chromosomes may affect Fb*.The results provide useful information to enhance the color quality of wheat flour in wheat.
