Evaluating barley genotypes for yield stability using integrated model- and rank-based stability statistics.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Barley (Hordeum vulgare L.) is one of the oldest domesticated cereal crops and remains a key component of global food and feed systems. As with other major crops, understanding genotype × environment (GE) interaction is crucial for improving yield stability and adaptability under diverse agroecological conditions. In the present study, a panel of 20 barley genotypes–comprising eighteen breeding lines and two local reference varieties–was evaluated for low-temperature tolerance and grain performance across eight cold-climate locations in Iran over two consecutive growing seasons (2020–2022). Combined analysis of variance (ANOVA) and the Additive Main Effects and Multiplicative Interaction (AMMI) model revealed significant effects of genotype (G), environment (E), and their interaction (GEI) on grain yield. AMMI-biplots (I and II) identified genotypes G18 and G19 as high-yielding and more stable than the remaining genotypes. Multiple stability parameters, including rank-based and model-based stability indices, consistently highlighted genotypes G2, G3, G9, G10, G15, and G18 as the most stable performers across environments. According to Annicchiarico's method and the AMMI-II biplot, the Hamadan location (environments E4 and E7) was identified as the most favorable testing environment. Spearman’s rank correlation analysis grouped the various stability statistics into three major clusters. Among these, stability parameters such as S3, S6, and KR showed positive and significant correlations with grain yield, reflecting a dynamic interpretation of stability. In conclusion, genotype G18 (Bahtim7DL/79-W40762//DeirAlla106/3/Bahman), characterized by an LT50 value of –9 and was identified as a promising candidate for cultivation in cold-climate regions of Iran, combining both high yield potential and strong cold tolerance.
