Phenotypic evaluation of local rice (Oryza sativa L.) landraces for tolerance to submergence stress.

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
Rice seedlings are often subjected to abiotic stresses, particularly flooding and submergence in lowland areas, highlighting the need to develop genotypes with improved tolerance to these conditions. This study aimed to evaluate the submergence tolerance of seven rice genotypes and identify adaptive traits associated with survival under complete submergence. Seven genotypes were phenotypically evaluated under complete submergence (155 cm water depth, 10 days) in a Completely Randomized Design (CRD) with nine replications. After a seven-day recovery period, the landraces were evaluated for survival, shoot elongation, biomass accumulation, green leaf retention, and chlorophyll content. All variables across stages showed significant genotypic variation (P ≤ 0.001), suggesting that the landraces used different adaptive methods. Sawa Mansuli Sub-1 and Chamse 6-mahine showed minimal elongation, superior leaf retention, higher chlorophyll content, and significantly greater survival; excessive shoot elongation, especially in Chamse 3-mahine, was linked to high biomass accumulation during submergence but highest mortality after recovery. Principal component analysis distinguished quiescence-type landraces (Sawa Mansuli Sub-1, Chamse 6-mahine, and Seto Bikashi) from susceptible escape-type landraces, with PC1 and PC2 explaining 95.8% of total variation. Correlation analysis revealed a negative association between shoot elongation and survival and positive associations between survival and post-recovery biomass, green leaf retention, and chlorophyll content. Although field testing and genetic research are still required, these results indicate that Chamse 6-mahine and Seto Bikashi are promising local rice varieties for creating flood-tolerant rice. Furthermore, they highlight quiescence-based energy conservation, chlorophyll content, and leaf viability as important determinants of submergence tolerance.
