Genetic Dissection of Protein Content in Cowpea Using NIRS and GWAS

A genetic study of grain protein content in cowpea (black-eye pea), a key crop for food security. The dataset includes evaluations of 287 diverse cowpea accessions using a species-specific near-infrared spectroscopy model. It was authored by Esteban Fernando Rios and last updated in April 2026.

Use Cases

• Conducting genome-wide association studies (GWAS) based on protein content phenotypes
• Developing predictive models for crop nutritional traits based on spectral data
• Training students in genetic analysis and plant breeding methodologies based on real-world phenotypic data

Strengths

• Includes 287 diverse cowpea accessions, providing genetic breadth
• Uses a species-specific near-infrared spectroscopy model described as having high accuracy

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
