Agro-Morphological Traits of Gamma-Irradiated Early Flowering Rice Mutants

Indonesia-based research characterizes eight early flowering rice mutant lines derived from the local Talang Sirah variety via gamma irradiation. The dataset includes field trial measurements for agro-morphological and yield traits, with mutants flowering 26 to 34 days earlier than the wild type. It was authored by Ita Dwimahyani and last updated in May 2026.

Use Cases

• Analyze correlations between flowering time and grain yield based on mutant performance data.
• Compare agro-morphological traits of mutant lines using principal component and cluster analysis methods described.
• Identify high-yielding rice genotypes based on grain yield per hectare measurements exceeding 8.2 t ha⁻¹.
• Study the effect of gamma-ray irradiation on genetic variation for early flowering in local germplasm.

Strengths

• Includes specific yield data, with four mutants yielding over 8.2 t ha⁻¹ compared to wild type (5.2 t ha⁻¹) and a national variety (6.47 t ha⁻¹).
• Documents a clear mutagenesis method using a 300 Gy dose of gamma rays from cobalt-60.
• Analysis is detailed, employing correlation, PCA (explaining 87.32% variance), and clustering (silhouette score 0.45).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is specific to one local variety (Talang Sirah) from Solok, Indonesia, limiting generalizability.
