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

backgroundThe widespread cultivation of water-saving and drought-resistance rice (WDR) represents a crucial strategy for sustainable agriculture in water-limited environments. Hanyou73, an elite WDR hybrid derived from the restorer line Hanhui3, exhibits outstanding drought resistance and stable yield performance. However, its susceptibility to blast, bacterial blight (BB), and brown planthopper (BPH) constrains its long-term cultivation stability.

resultsThree major resistance genes Pi9 (blast), Xa23 (BB) and Bph6 (BPH) were successfully pyramided into Hanhui3 via marker-assisted backcross breeding. The resulting improved line, Hanhui303, retained 96.68% of the recurrent parent genome (RPG). Furthermore, Hanhui303 and Hanhui3 were indistinguishable using 48 standard SSR markers for variety identification. Hanhui303 and its hybrid rice conferred resistance to both blast, BB and BPH. The major important agronomic traits and grain quality of Hanhui303 and its hybrid rice obtained in field trials were similar to those of Hanhui3 and the control hybrid rice.

conclusionsWe developed a novel restorer line, Hanhui303, with significantly enhanced resistance to three major biotic stresses while maintaining the elite agronomic and drought resistance traits of Hanhui3. Due to its high genetic similarity and identical fingerprint profile, Hanhui303 can directly replace Hanhui3 in hybrid seed production. This study provides a practical and efficient strategy for improving multiple resistances in elite parental lines, thereby promoting the sustainable cultivation of WDR hybrids.
