Phenotypic Plasticity of Reproductive Traits in 100 Korean Rice Cultivars

100 Korean rice cultivars from three maturity groups were assessed for phenotypic plasticity of key reproductive traits. Measurements were taken from a controlled greenhouse environment and two contrasting field environments in a dry year (2018) and a wet year (2020). The dataset, created by Joon Ki Hong and last updated in March 2026, uses Z-score standardization and kernel density estimation to analyze trait distributions and environmental shifts.

Use Cases

• Compare panicle length and seed number variability across maturity groups based on the described trait measurements.
• Model the influence of climatic factors like rainfall on reproductive trait expression using the multi-environment data.
• Identify cultivars with high buffering capacity or environmental sensitivity for breeding programs based on the described maturity-dependent plasticity.
• Benchmark panicle development and yield potential under controlled versus field conditions as described in the study.

Strengths

• Includes data from 100 distinct Korean rice cultivars.
• Combines measurements from a precision-controlled greenhouse with two contrasting field environments (2018 dry year, 2020 wet year).
• Specific trait ranges are provided, such as panicle length 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 dataset is small at 12.5 KB, indicating limited scope.
