Screening of historical and current Upland and Pima cotton germplasm for resistance to Rhizoctonia solani.
Article in BMC research notes, 2025. 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
objectiveThe fungus Rhizoctonia solani is an important seedling pathogen to many plant hosts including cotton (Gossypium). For multiple annual crops there have been relatively few screenings of germplasm conducted to identify potential sources of resistance to R. solani, and for cotton we have not been able to identify any recent germplasm screenings for resistance to this seedling pathogen. Therefore, the objective of this study was to screen historical as well as more recently developed Upland (Gossypium hirsutum L.) and Pima (Gossypium barbadense L.) cotton germplasm for resistance/susceptibility to R. solani.
resultsThe results of the R. solani screening found no significant differences among 85 Upland and 10 Pima cotton genotypes, which were all similarly susceptible to R. solani based on data for root rot and fresh root weight. While Upland and Pima cotton make up the majority of cotton grown worldwide, the lack of resistance identified in both historical and newer Upland and Pima germplasm suggests a pressing need for further exploration and selection of novel sources of resistance within the vast genetic diversity of different domesticated and wild cotton species.
