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

Introduction: Seed shape and hundred-seed weight (HSW) are yield-related traits, but the interrelationships between them and a systematic genetic analysis are lacking. Methods: In this study, phenotypic evaluation of seed shape-related traits and HSW was performed in a recombinant inbred line (RIL) population derived from the cross between "ZD41" and "ZYD02878." All seed shape-related traits (SW, seed width; SL, seed length; ST, seed thickness; SP, seed perimeter; SA, seed area; SLW, seed length-to-width ratio; SLT, seed length-to-thickness ratio; SWT, seed width to thickness ratio) were evaluated. Broad-sense heritability was calculated. Correlation analysis, path analysis, QTL mapping (using ICIM, EMMAX, and TASSEL), and genomic selection (using rrBLUP) were performed. Results: All seed shape-related traits exhibited approximately normal distributions in the RIL population. The broad-sense heritability of seed shape-related traits ranged from 0.67 to 0.90, indicating that additive genes played a major role in expressing all studied traits. Correlation analysis revealed that SW showed the highest positive correlation with HSW (r = 0.86-0.87, P < 0.001) among the three measured seed shape-related traits (SL, SW, and ST), which agrees with the finding that SW was the only trait showing a positive direct effect on HSW in path analysis. A total of 98 QTL corresponding to 59 unique regions were identified by ICIM, EMMAX, and TASSEL. Three genes, Discussion: This study provided a systematic dissection of seed shape-related traits in terms of both phenotypic and genetic aspects, which laid a solid foundation for gene cloning and could be used in breeding programs in the future.
