Genetic diversity between local landraces and current breeding lines of pepper in China.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Based on 22 qualitative traits, 13 quantitative traits, and 27 molecular markers (26 SSR and 1 InDel), in the current study we compared the diversity and population structure of 94 local landraces and 85 current breeding lines of pepper in China. The results showed that the Shannon Diversity indices of 9 qualitative traits and 8 quantitative traits in current breeding lines were greater than those of landraces, of which 11 were fruit organ-related traits. Compared with current breeding lines, the mean values of Gene Diversity index and Polymorphism Information content of local landraces were higher by 0.08 and 0.09, respectively. Population structure and phylogenetic tree analysis showed that the 179 germplasm resources could be divided into two taxa, dominated by local landraces and current breeding lines, respectively. The above results indicated that the diversity of quantitative traits of current breeding lines were higher than that of local landraces, especially traits related to fruit organs, but the genetic diversity based on molecular markers was lower than that of local landraces. Therefore, in the future breeding process, we should not only focus on the selection of target traits, but also strengthen the background selection based on molecular markers. Moreover, the genetic information of other domesticated species and wild species will be transferred to the breeding lines through interspecific crosses to expand the genetic background of the breeding material.
