Turmeric Half-Sib Progeny Yield and Trait Data from a Two-Year Field Trial

263 first-generation seedling-derived half-sib progenies of turmeric were evaluated alongside three checks in a two-year field trial (2024–2025) in Kozhikode, India. The dataset includes measurements for 17 vegetative, rhizome, yield, and dry recovery traits, with high heritability reported for key yield components. Authored by Akkurthi Neeraja and shared under a CC-BY-4.0 license, this data supports the selection of superior turmeric genotypes.

Use Cases

• Selecting superior turmeric genotypes based on multi-trait selection indices like MGIDI and MTSI mentioned in the description
• Analyzing the relationship between vegetative growth traits and rhizome yield using structural equation modeling results
• Assessing genetic variability and heritability for yield components in seedling-derived turmeric progenies
• Investigating trade-offs between total yield and dry recovery percentage highlighted by correlation analysis

Strengths

• Data covers 263 progenies and 17 distinct traits, providing a basis for statistical analysis
• High broad-sense heritability (60–97%) reported for most traits, including total yield per plant (80.73%)
• Field trial conducted over two years (2024–2025), suggesting repeated measurements
• Strong positive correlations identified, such as between total yield and primary rhizome weight (r = 0.81)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is stored in a PDF format (92.3 KB), which may require extraction for computational analysis
