Evaluation of Pepper Cultivar Resistance to Alfalfa Mosaic Virus in Colorado

Data from a study evaluating 30 commercially available pepper cultivars for resistance to Alfalfa mosaic virus (AMV) in greenhouse and field conditions. The work was conducted by Lara Amiri-Kazaz, with field trials on commercial farms in Pueblo, CO, and the dataset was last updated on 2026-05-08. In the greenhouse, 10% of cultivars showed strong resistance and 25% displayed tolerance, while field trials showed half maintained low symptom severity.

Use Cases

• Compare host plant resistance levels among 30 pepper cultivars based on symptom severity and infection incidence data.
• Validate greenhouse resistance findings against field trial results under natural infection conditions.
• Identify pepper cultivars with innate resistance or tolerance for integration into pest management programs.
• Analyze temporal changes in susceptibility to AMV observed in specific cultivars.

Strengths

• Includes data from both controlled greenhouse mechanical inoculation and natural infection field trials on commercial farms.
• Evaluates a specific set of 30 commercially available pepper cultivars.
• Assesses infection through multiple methods: visual symptom observation and ELISA testing.

Limitations

• Dataset is very small at 21.7 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
