Segregation distortion caused by weak hybrid necrosis in recombinant inbred lines of common wheat.
Article in Genetica, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Segregation distortion of molecular markers is closely related to hybrid incompatibility in progeny from intraspecific crosses. Recent reports in higher plants have demonstrated that hybrid sterility results in segregation distortion at the causal gene regions in progeny of intraspecific crosses. Ne1 and Ne2 complementary loci are known to control hybrid necrosis in intraspecific crosses of common wheat cultivars. Here, we examine the effect of a weak necrosis allele Ne1(w) on the segregation ratio of molecular markers in recombinant inbred lines (RILs) of common wheat. Some RILs showed accelerated cell death in the leaves at the heading stage due to the epistatic interaction between two quantitative trait loci (QTL) on chromosomes 5B and 2B. Chromosomal localization of these QTL corresponding to Ne1(w) and Ne2 showed distorted segregation ratios of assigned markers having oppositely biased direction. Although the Ne1(w) and Ne2 interaction had no obvious effect on seed fertility, Ne1(w) reduced completion of grain development under the Ne2-homozygous background. This reduction might be one of causes that induces segregation distortion in the 5B and 2B chromosomal regions of RILs. The present study demonstrated that weak hybrid necrosis has limited phenotypic effects; it causes segregation distortion in progeny from intraspecific crosses.
