Korean Rice Cultivar Reproductive Traits Under Diverse Climatic Conditions

Data Sheet 1 by Joon Ki Hong, last updated March 2026, contains a dataset evaluating phenotypic plasticity in 100 Korean rice cultivars across three maturity groups. Measurements of reproductive traits like panicle length and seed number were taken from a controlled greenhouse and contrasting field environments in a dry year (2018) and a wet year (2020). The analysis uses Z-score standardization and kernel density estimation to reveal environmental influences on trait expression.

Use Cases

• Modeling the relationship between climatic factors and panicle length based on measurements from controlled and field environments.
• Comparing seed number per panicle across early, medium, and late-maturing rice cultivar groups.
• Analyzing trait distribution shifts using Z-score standardization and kernel density estimation methods described in the study.
• Assessing environmental sensitivity and buffering capacity of different rice maturity groups under variable rainfall conditions.

Strengths

• Includes data for 100 distinct Korean rice cultivars.
• Combines measurements from a precision-controlled greenhouse with two contrasting field environments (2018 dry year, 2020 wet year).
• Analyzes three distinct maturity groups (early, medium, late).
• Reports specific trait measurements, such as panicle length ranging from 17.99 cm to 22.10 cm.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a PDF (174.0 KB), which suggests a small, likely summary dataset rather than raw experimental data.
