Phenotypic variability of plant architecture, easy destemming, and yield for accelerated selection for mechanical harvestability in chile pepper.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In recent years, chile pepper (Capsicum annuum L.) production in the US has shown a decline due to higher costs associated with manual harvesting and unavailability of skilled labor. Chile pepper breeding programs have incorporated mechanization as a long-term breeding objective alongside historically significant traits such as yield, disease resistance, and fruit quality. Nevertheless, information on the genetic landscape of traits crucial for chile pepper mechanization and their relationships with other agronomic traits remain limited. This study employed multivariate approaches, phenotypic and genetic correlations, hierarchical cluster analysis (HCA), and principal component analysis (PCA) to investigate the genetic architecture of mechanical harvestability traits using a diverse C. annuum L. population evaluated in field conditions in New Mexico, USA. Fruit morphology and fruit destemming force were the most discriminating traits that accounted for most of the observed phenotypic variation in the population. Medium to high narrow-sense heritability estimates (0.53-1.0) indicated the predominance of additive genetic effects for traits relevant for mechanical harvesting. Negative genetic correlations (r
