Genetic variation among pumpkin landraces based on seed qualities and molecular markers.
Article in Molecular biology reports, 2022. 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
backgroundGermplasm identification is an essential connection linking the conservation and exploitation of crop genetic resources in several plant breeding programs. This study highlights the biochemical and molecular variations in a collection of pumpkin genotypes representing four climate zones. The information could help improve germplasm management and sustainable exploitation of the neglected genotypes. METHODS AND
resultsChemical characterization and genetic diversity among nine Egyptian landraces of pumpkin (Cucurbita moschata Duchesne) were estimated using Diode Array (DDA) Near Infra-Red (NIR) technology and the Inter simple Sequence Repeat markers (ISSR). Pumpkin seeds were collected from various geographical parts of Egypt. The spectroscopic properties of pumpkin seeds were used to quantify the fat, moisture, protein, ash, fiber, and total carbohydrate contents. The ten ISSR primers generated a total number of 46 genotype-specific bands, and the total polymorphism produced in the tested landraces was 63.58%. Based on the ISSR data, the polymorphism analysis divided the nine pumpkin landraces into two main groups, two subgroups, and four sub subgroups. The most diverse pumpkin landraces were Alexandria and Sohag, with a similarity percentage of 49.6%. However, the highest calculated similarity value was 88.3% between Matruh and Gharbia. The resultant genotype-specific bands can be used as markers for future genotypic characterization of pumpkins.
conclusionsThe study results could be helpful in the chemical phenotypic characterization and the parental selection and planning for future breeding programs for pumpkin improvement.
