1 · What the graph read from it

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.

2 · The registry

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

backgroundRice is susceptible to several major and minor diseases, with blast disease caused by Magnaporthe oryzae being a significant constraint, leading to substantial economic losses worldwide. Exploiting genetic resistance in cultivars is a preferred strategy for managing this disease, offering an alternative to chemical control. METHODS AND

resultsThe objective of this study was to identify advanced breeding lines (ABLs) with blast resistance, superior yield, and good grain quality using Marker-Assisted Selection (MAS). Leaf blast resistance screening revealed that 25 ABLs exhibited moderate resistance. Molecular analysis with 10 polymorphic markers linked to blast resistance genes (Pi1, Pi2, Pi9, Pi37, Pi38, Pi39, Pi54, Pita, Pitp, and Piz5) identified the highest number of positive alleles (8) in MTU1061, IR36, and SVGP-26. Additionally, seven ABLs (SVGP-1, SVGP-14, SVGP-23, SVGP-37, SVGP-38, SVGP-39, and SVGP-48) showed co-segregation of markers with blast resistance. Genetic diversity analysis revealed significant variability among the genotypes, indicating diverse genetic backgrounds. Based on their yield performance, quality traits, and resistance to blast, five parents (NLR 34449, NLR 40024, MTU 1061, MTU 3626, and IR 36) and five ABLs (SVGP-13, SVGP-16, SVGP-40, SVGP-47, and SVGP-32) were selected for further yield trials.

conclusionThe study identified high-yielding, blast-resistant lines with good grain quality and diverse genetic backgrounds as promising donor sources for improving blast resistance in rice breeding programs. These findings enhance the genetic base for developing resistant rice cultivars with improved agronomic traits.
