Potato Cyst Nematode Resistance Test Data for 28 Varieties

Eight populations of the potato cyst nematode Globodera pallida were tested on 28 potato varieties in standardized resistance experiments. The dataset includes columns for population, variety, replicate, inoculation count, final cyst count, and the calculated reproduction rate (Pf/Pi). It was authored by Arno S. Schaveling and last updated on figshare in May 2026.

Use Cases

• Classifying potato variety resistance levels based on the Pf/Pi reproduction rate.
• Comparing virulence across different G. pallida populations based on the population column.
• Analyzing experimental repeatability based on the replicate column.
• Grouping potato varieties for breeding using the pre-determined cluster assignment.

Strengths

• Data is from standardized PCN resistance tests, suggesting a controlled experimental method.
• Includes a calculated reproduction rate (Pf/Pi), a key metric for resistance assessment.
• Potato varieties are grouped into clusters from prior research, providing additional context.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 52.4 KB, indicating limited scope.
