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

Tiller number is a key factor influencing wheat plant architecture and yield potential. This study analyzed the variation in tiller number among 323 wheat accessions across nine environmental conditions. The results revealed a significant decrease in tiller number in modern cultivars compared to traditional landraces, indicating a trend in selective breeding for fewer tillers. Genome-wide association studies (GWASs) identified four quantitative trait loci (QTLs) associated with tiller number on chromosomes 2D, 5A, and 6A. Haplotypes linked to reduced tiller number at three of these QTLs have been significantly selected and are predominantly found in various Chinese agroecological zones, positively affecting grain number and/or weight. These findings suggest that contemporary Chinese wheat breeding strategies have prioritized reducing tiller number while improving spike yield. Identifying selected haplotype combinations can further enhance breeding efforts aimed at optimizing the tiller number trait. This study provides insights into the genetic basis of tiller number QTLs and their relevance to wheat breeding practices.
