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

Spike traits play a pivotal role in determining wheat yield. In this study, two recombinant inbred line (RIL) populations were employed to identify quantitative trait loci (QTLs) for spike length (SL), spikelet number per spike (SNS), and basal sterile spikelet number (BSSN). A total of 30 QTLs were identified, including 7 major-effect QTLs that exhibited stability across multiple environments. Among these, two novel QTLs were discovered: QBssn.A-3 A.3 and QBssn.AV-5B.2. Furthermore, it was found that the combination of these two QTLs with other major effect QTLs had no impact on thousand-kernel weight (TKW). For QBssn.A-3 A.3, a Kompetitive Allele-Specific PCR (KASP) marker was developed and validated based on its physical location. Additionally, candidate genes within the intervals of QBssn.A-3 A.3 and QBssn.AV-5B.2 were predicted, based on these genes primarily associated with sterile spikelet number per spike. This study provides a foundation for future map-baesd cloning of genes related to spike traits, and for the breeding of high-yield wheat varieties.
