Evaluation of the progeny produced by interspecific hybridization between Camelina sativa and C. microcarpa.
Article in Annals of botany, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
BACKGROUND AND
aimsCamelina (Camelina sativa, Brassicaceae) has attracted interest in recent years as a novel oilseed crop, and an increasing number of studies have sought to enhance camelina's yield potential or to modify the composition of its oil. The ability of camelina to cross-hybridize with its wild relative, C. microcarpa, is of interest as a potential source of genetic variability for the crop.
methodsManual crosses were performed between the crop C. sativa and its wild relative C. microcarpa; F1 and F2 progenies were obtained. Cytology was used to study meiosis in the parents and F1s and to evaluate pollen viability. Flow cytometry was used to estimate nuclear DNA amounts and fatty acid methyl ester analysis was used to evaluate the lipid composition of F3 seeds. KEY
resultsThe F1 plants obtained by interspecific crossing presented severe abnormalities at meiosis and low pollen viability, and produced very few F2 seeds. The F2s presented diverse phenotypes and in some cases severe developmental abnormalities. Many F2s were aneuploid. The F2s produced highly variable numbers of F3 seeds, and certain F3 seeds presented atypical lipid profiles.
conclusionsConsidering the meiotic abnormalities observed and the probability of aneuploidy in the F2 plants, the C. microcarpa accessions used in this study would be difficult to use as sources of genetic variability for the crop.
