Macadamia Self-Incompatibility Phenotypes from Four-Year Field and Microscopy Study

A four-year study by Guanghong Kong, published in 2026, characterizes self-incompatibility in macadamia germplasm. The dataset identifies 23 varieties classified by strength of self-incompatibility using field-bagging and fluorescence microscopy methods. It provides a foundation for breeding self-compatible macadamia varieties to improve crop yield.

Use Cases

• Classifying macadamia varieties by self-incompatibility strength based on the final self-incompatibility index (F_SI).
• Validating fluorescence microscopy as a cost-effective SI identification method based on pollen tube length percentage (PLS).
• Screening germplasm resources for self-compatible breeding candidates based on the identified strong, medium, and weak SI varieties.

Strengths

• Provides a standardized classification system for self-incompatibility with defined thresholds for F_SI and PLS.
• Results from a four-year field study, suggesting longitudinal observation.
• Identifies 23 specific macadamia varieties with their SI classifications.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (22.1 KB), indicating limited scope.
