Inter-annual and regional variability of agronomic and grain quality traits of major Korean wheat cultivars under multi-environmental conditions.
Article in Journal of the science of food and agriculture, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWheat agronomic performance and grain quality vary substantially depending on environmental conditions. However, few studies have evaluated agronomic performance, grain quality stability, and growth stage-specific climatic regulation together across representative Korean wheat-production environments.
resultsPhenological traits and amylose content showed relatively high stability across multiple environmental conditions, whereas yield components and protein-related quality traits exhibited pronounced environmental variability. Climatic gradients integrating radiation, temperature, and moisture structured environmental differences and were differentially associated with crop responses across growth stages. Early season climate primarily influenced phenological development, whereas climatic conditions during reproductive growth exerted the strongest control over yield formation and protein-related traits. An integrated grain quality index further showed that environmental effects were reflected through changes in overall quality performance and differences in interannual stability.
conclusionVariations in wheat performance and grain quality across different environments were governed by structured climatic gradients and developmental timing rather than by isolated site effects. This study provides an analytical framework for distinguishing stable and environment-sensitive wheat traits by integrating multi-environment field trials, growth stage-specific climate gradients, and composite grain quality assessment under Korean agro-climatic conditions. © 2026 The Author(s).
