Genome-wide assessment of genetic diversity and population structure of Capsicum in Southwestern Colombia using DArTseq markers.
Article in PloS one, 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
Chili peppers (Capsicum spp.) are among the most widely cultivated horticultural crops worldwide due to the high demand for their pungent fruits. Despite Colombia's high diversity of Capsicum species and varieties, its genetic resources remain underrepresented in international markets and scientific studies. This study aims to characterize the genetic diversity and population structure of Capsicum accessions from southwestern Colombia. Accessions were collected through field surveys in local markets and protected natural areas and genotyped using DArTseq platform. A total of 69 accessions representing seven species were genotyped using 3681 high quality DArT-SNP markers. Standard genetic diversity metrics and population structure analyses were performed. The analysis revealed low observed heterozygosity (mean 1%) and high inbreeding coefficients (FIS: 0.24). However, expected heterozygosity values indicate that these accessions still retain substantial genetic variability, highlighting their potential for breeding and genetic improvement programs. Population structure analysis revealed clear genetic differentiation between Andean and domesticated Capsicum species. Moreover, Silico-DArT markers could discriminate between wild and domesticated accessions within C. annuum and C. frutescens. This study represents the first genome wide assessments of Andean Capsicum species using DArTseq genotyping. These findings contribute to the understanding and conservation of Capsicum genetic resources of Southwestern Colombian and provide valuable information for future breeding programs.
