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

Spikelet number per spike (SNS), a key determinant of grain yield in wheat, is a complex quantitative trait controlled by spike meristem activity. Unraveling its genetic basis is essential for wheat high-yield breeding. Here, we identified a stable quantitative trait locus (QTL), QSNS.sicau-D12-3B, governing SNS using a recombinant inbred line (RIL) population derived from a cross between the high-SNS line 03D501 and the low-SNS line 2011. This QTL was consistently detected across seven environments and mapped to a 5.814 Mb interval on chromosome 3B (flanked by markers K_sau_3B_619673521 and K_sau_3B_625487833). Conditional QTL analysis revealed that QSNS.sicau-D12-3B acts independently of plant height and spike length but may modulate SNS through its effect on spike density. Validation in diverse genetic backgrounds confirmed the robust association between QSNS.sicau-D12-3B and SNS, underscoring its potential for yield improvement. Our findings provide novel insights into the genetic architecture of SNS and offer a promising target for molecular breeding in wheat.
