1 · What the graph read from it

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.

2 · The registry

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

objectivesTo facilitate the innovation and efficient utilization of specialty maize germplasm, this study aimed to systematically evaluate a panel of 222 inbred lines. The objective was to comprehensively characterize phenotypic variation, genetic diversity, and genotype-phenotype associations to screen for representative germplasm resources.

methodsWe integrated Best Linear Unbiased Prediction (BLUP) values derived from multi-environment field trials with high-density whole-genome single-nucleotide polymorphism (SNP) data. Population structure and genetic diversity were analyzed, Mantel tests were conducted to assess genotype-phenotype correspondence, and a genome-wide association study (GWAS) was performed to identify significant loci.

resultsThe population exhibited substantial phenotypic variation, particularly in plant height and tassel traits, with distinct morphological differentiations among specialty types. Genetic diversity analyses revealed varying diversity levels among subpopulations. While Mantel tests indicated a weak overall genotype-phenotype correspondence, specific traits showed significant associations with genetic distance. GWAS successfully identified significant loci associated with plant height and tassel traits. Furthermore, population structure analysis revealed distinct genetic stratification corresponding to specialty types, albeit with a certain degree of admixture.

conclusionsBy integrating multi-dimensional phenotypic and genomic profiles, a panel of highly diverse and representative candidate germplasm was identified. These findings provide a crucial theoretical basis for specialty maize breeding and the optimized utilization of germplasm resources.
