Inducing fixation of transgenic alleles in open-pollinated populations.
Article in Transgenic research, 2026. 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
The progeny of chlorsulfuron-resistant forage rape (Brassica napus L. subsp. napus, cv. Giant) and potato (Solanum tuberosum L. cv. Iwa) plants hemizygous for a single transgenic locus were screened for transgene segregation following an application of either water or chlorsulfuron. The transgenic locus contained three transgenes conferring kanamycin resistance (NOS-NPTII-NOS), β-glucuronidase (GUS) activity (35S-GUS-OCS), and chlorsulfuron resistance (a complete acetohydroxyacid synthase gene with a proline197 to serine substitution). In the absence of the herbicide application, plants segregated for GUS activity as expected for single locus inheritance. However, the progeny of plants sprayed with chlorsulfuron exhibited a highly distorted segregation for GUS activity, with a significant excess of transgenic progeny. Inducing such biased segregation provides a simple treatment to rapidly drive the fixation of transgenic alleles to homozygosity in open pollinated populations during seed increases of new cultivars.
