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

The production and use of doubled haploid (DH) lines have gained a significant momentum in maize breeding worldwide due to several advantages they offer over conventional inbred lines. The use of genetically homozygous DH lines simplifies the breeding operations, offers significant time and cost savings, and facilitates greater integration of molecular marker applications to increase selection intensity and genetic gains. The production of DH lines in maize includes several steps, including in vivo production of maternal haploids using appropriate haploid inducers, identification of haploid seeds from the diploid seeds, germination of putative haploid seeds, treatment of the putative haploid seedlings with antimitotic chemicals to double the chromosome number, and seed production from the putative doubled haploids. This chapter outlines the materials and methods used at different steps in maize DH line production.
