Discovering putative novel stem rust resistance loci in wheat genetic resources.
Article in The plant genome, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Stem rust (SR), caused by Puccinia graminis f. sp. tritici (Pgt), poses a threat to wheat production in Germany. This study evaluated 200 plant genetic resources (PGR) and 50 elite lines across four field environments. Multi-environment genome-wide association mapping based on PGR accessions revealed 1942 marker-trait associations (MTAs), grouped into eight quantitative trait loci (QTLs), which explained 0.84%-28.19% of phenotypic variance. Three of these QTL, QSr1B_1.47_67.79, QSr4A_716.31_716.32, and QSr7D_171.80_174.34, harbor five haplotypes that have likely not been used in breeding. Five representative MTAs (Chr1B:25506861, Chr1B:17349639, Chr1B:67755088, Chr4A:716319007, and Chr7D:171807054) represent these five putative novel haplotypes, and together they conservatively explained 2.40%-7.03% of the phenotypic variance. Four genotypes carrying all favorable alleles of the representative MTAs were identified as potential donor lines for future breeding. Within eight QTL regions, 44 candidate genes were prioritized. These findings provide new insights into the genetic architecture of SR resistance and highlight promising targets for marker-assisted prebreeding.
