Maternal doubled haploid production in interploidy hybridization between Brassica napus and Brassica allooctaploids.
Article in Planta, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
MAIN
conclusionWe found a new in vivo route to produce maternal doubled haploid of Brassica napus . The pollen donor, an allooctaploid rapeseed, acts as a DH inducer. Inbred line has a powerful advantage in cultivar breeding and genetic analysis. Compared to the traditional breeding methods, doubled haploid production can save years off the breeding process. Though genotype-dependent tissue culture methods are widely used in the Brassica crops, seed-based in vivo doubled haploid developing systems are rare in nature and in the laboratory. As interspecific cross and interploid hybridization play an important role in genome evolution and plant speciation, we created a new Brassica artificial hybrid, a Brassica allooctaploid (AAAACCCC, 2n = 8× = 76), by interspecific crossing and genome doubling. A homozygous line was observed at the third self-generation of a synthesized Brassica allohexaploid (AAAACC, 2n = 6× = 58). Crosses between B. napus as female and Brassica allooctaploid as pollen donor were conducted, which yielded maternal doubled haploid B. napus that were identified based on phenotype, ploidy, and molecular analysis. The Brassica octaploid acted as a maternal doubled haploid inducer and had a relatively high induction rate. Our research provides a new insight for generation of homozygous lines in vivo using a single-step approach, as well as promotes the understanding in breeding programs and genetic studies involving the Brassicas.
